What few people understand about hook and carry
« on: June 29, 2012, 09:19:29 PM »
Another post about the most hookiing ball promoted me to finally make this post that I have been considering for a long time. 

People understand that it is necessary to minimize deflection on pocket hits to maximize carry.  What they don't understand is that additional entry angle in and of itself does not reduce deflection, it merely changes the angle of deflection.  The best example of this is the pocket 7-10 which was rare 40 years ago before bone dry back ends and high friction shells became the norm.  The 7-10 is a result of a ball that has good entry angle but lacks rotational energy ( rolls out )   

  In order for a ball to actually deflect less, it must still be releasing rotational energy as it enters the pocket, regardless of how much entry angle is achieved.  A high rev release with low axis rotation, that still has rotational energy will deflect less and carry better than a ball with stronger entry angle but little or no rotational energy remaining.

Why is this an important concept?   Because if people really understood it, nobody would care what the biggest hooking ball was anymore.  Rather they would care about what core and shell matchup would allow their roll pattern to release rotational energy at the proper place for any given amount of oil.  Heavier longer oil is best attacked by stronger end over end roll and a straighter trajectory.

 As time goes by, I find that the newer bowlers know less and less about the game, or the physics of why bowling balls knock pins over to begin with.

 Go back, and watch some of the videos of bowlers from the 1950's, 60's, 70's, and 80's, and you will easily see that entry angle isn't everything.

 Carry is about the path the ball takes as it goes THROUGH the pins, not the angle it hits the headpin. It can hit the headpin perectly, but have too much drive(or deflection), and end up going through the pins improperly to create carry on a consistent basis.

Can't blame the kids for what they have never seen I guess.  After all it dawned on me that the resin era is now 20 years old.  Everyone always talks about entry angle but it is really revs and roll that fight deflection not entry angle.  Any old guys out there are familiar with the term fall back shot.   We use to see it a lot on wood lanes before urethane balls and short oil came into vogue.  You could set a plastic or even rubber ball down inside 4th arrow with a break point barely to the right of 15 and shoot big scores.  I once shot 790 760 back to back with a yellow dot playing that angle in an old tracked out wood house, and blew out a few 5 pins along the way.  I obviously didn't need much entry angle to carry.

I had a Yellow Dot and a Dick Weber Powerball for strikes and a Blue Dot for a spare ball back in the '70's.  I played an outside line because I watched Earl Anthony and thought he was the best around (so I always wanted to be like Earl).  This was all on wood lanes and I usually scored well - but I'm still trying the figure out the new lane conditions we have now.

I remember well the first synthetics around 1980.  The shot didn't really play that much different than on the hard urethane finish used on wood, but it did break down fast.  Saw a lot of 4 baggers stopped on well thrown balls that went 4-6.  Biggest change in the 80's was the trend to very short oil patterns ( 24-28 feet ).  Those short patterns really provided a launching pad for the new crankers that took over the game during that decade.  The introduction of the resin balls forced lane men to increase the volume and buff length of oil dramatically to combat the friction created by the resin covers. 

The biggest difference from a bowlers point of view today, is the much greater ball speed that is necessary to get a good ball reaction.  In the 60's and 70's speed was a killer because there wasn't enough friction between the ball and the lane to allow it to come out of a skid if the speed was too high.  Today there is so much friction that it takes more speed to keept the ball from rolling out.

Big Hooking Ball is what most want in my area. What I see a lot on the lanes is super high speeds and very low revs.

You only need about 6 degree of entry angle for a strike!! The high revs, no thumbers and super strong cover and cores sometimes is way to much for today's conditions! I see a lot of these guys leave 8-10's, 7-9's, 4-9's, and 7-10's and when they get wound up about how great a shot it was. I try to explain to them that it happens with so much hook and entry angle. They can't understand that the ball was dead when it hit the pocket!!! I've been bowling since the 60's and have seen a big transition in lanes, oil, patterns, and bowling balls. The new bowlers now don't have a clue unless they watch older bowling videos or see ESPN Classic bowling from the 70's and 80's!!!

We are all products of  our environment in the game.  When I was young and learning the game my style was influenced by the greats of the era like Ray Bluth, and later Jim Stefanich.  I loved the pure strokers, and it was an effective style to mimic on the lacquer finish I learned on.


The introduction of urethane lane finish really promted the revolution in the game that culminated in the of the power style favored by so many bowlers today.  Urethane replaced lacquer because it was lower maintenance, and safer to work with when resurfacing.  However, the oiling techniques used on lacquer produced a very difficult lane condition as the oil migrated down the lane rather than tracked out from the friction of ball releases.  Lanemen responded by making use of heavy crowns, and tried to strip the back ends more regularly.  The discovery that polyester balls reacted much better on the urethane surface promted the first boom in scoriing in the mid 70's ( actually more drastic than the introduction of either urethane or resin in later years ).  The ABC responded by mandating flat oil patterns that caused many bowlers to become totally contemptuous of the ruling body.  Lanemen struggled to put out playable conditions under the mandates of flat oil by continually shortening the oil patterns and stripping the back end, sometimes several times a week.  Youngsters who liked to hook the ball found that the screaming back ends allowed them to develop a high rev big hooking release that carried so well on the short oil patterns that spares became an after thought. 

All this was excaserbated in the eighties when that ABC, in less than infinite wisdom mandated even shorter oil, in the mistaken belief that the new breed of power players were getting their scores by using the oil to steer the ball into the pocket.  All this did was provide a launching pad in the heads for bowlers to create all the revs and hook imaginable on the screaming dry back ends. 

By the time the system of bowling replaced the short oil mandate in the late 80's, the environment favoring the cranking style had been around for almost 15 years.  The resin ball was introduced shortly thereafter, making the oil pattern mandated by the system of bowling meaningless.  The 3 units of oil required on the outside boards provided an effective out of bounds for urethane balls, but the resin balls hooked through such a low volume like it wasn't there. 

When the sport patterns came into vogue the few straighter players remaining really had little trouble adjusting, but the guys who liked high revs and monstorous amount of hook were DOA.  Overkill revs and power had been the name of the game for so long that few young people understood that carry could also be maximized more efficiently by matching up speed and rev rates with a straighter delivery. 

The best example of the misunderstanding of the physics of the game today comes from those who think the resin ball favored the the low rev players.  The majority of younger bowlers think resin made Walter Ray Williams and Norm Duke.  In fact if Resin balls were suddenly outlawed without cutting back oil volumes and returning to extremely short patterns it is the power players who would suffer the most.
