What conditions is a Stacked Leverage drilling best used for?
« on: July 30, 2003, 05:42:21 AM »
Drillings like 3.5" x 3.5" and 4" x 4". What are the best oil conditions for this drilling?

Is it best for when you want to swing the ball? And where you want the biggest backend snap/hook?


Thanks!

Ric, anything stacked is going to give you the most unstable situation with the core.....obviously once you get to 5x5 things calm down a bit because of the flare potential or loss of...

3 3/8 x 3 3/8 is obviously full leverage stack ...most flare thru-out the entire lane......most hook out of a ball.  In general I like to think of 4x4, etc as an angular backend reaction, or more angular, sharp. With 33/8x33/8 being the most arcing of the stacked drills.  But of course it also depends on coverstock.....pearl resin more angular, particle less....etc.

Not sure if it suits a particular lane condition or style best, it's more of a definition of the hook shape of the ball.  I would think a fresh, medium heavy condition would be good, maybe mediums as well, also for heavier too.

There are a lot of factors here....sit tight..gurus will come chiming !

I have found pure stacked work great where it is blended or there is a crown.

Especially the 3 3/8 stacked.  Covers a lot of boards, starts in the heads, the ball must almost always be swung.  Hooks all the way down the lane, or attempts to hook, heads, mids and backend.

All stacked will try to get up high on the head pin,  in relation to most other drills.  If you start to see 4 pins, (or for lefty 6 pins) and you can't adjust off them, or pocket splits ready to happen, it is often times to switch to drills that do not maximize the core potential(the stacked drilling).

Kicked out cgs will increase midlane and decrease pure backend angle Hook set.
Kicked under grip cgs will decrease midlande and decrease backend angle from inside.

Many bowlers can not see the pins starting to fall slowly.  Fortunately at times I've been able to see it and switched to the less entry angle drillings above and been able to put a little cash in my pocket here and there.

On the other spectrum if the ball can't get high enough on the head pin it is often a great time to think about the stacked drilling.

PS I find all stacked drillings have the same flight charecteristics.
Whether 3 3/8, 4 X 4, 5 1/2 X 5 1/2, the ball must be swung a little in the heads and midlane.  The difference is only in the amount of total flair or boards covered!  3 3/8 the most, 5 1/2 the least.

One more question:

Will 3 3/8 x 3 3/8 hook earlier and arc more on the backend that a 4.5 x 4.5?

Which will go longer and have more snappy of a backend?

IN GENERAL, yes.

That depends on the type of ball and how you throw it.

A low tracker will always have more skid and more reaction in the back end - snappier.

A high tracker will have less skid and a more gradual grab - less snappy.

(I'll call 3 3/8" 3.5"[/] for the sake of typing brevity; I know 3 3/8" = 3.375"!)

For dull or matte finish balls (be they pearls, particle, solids or resins) the 4.5x4.5 will be snappier than a 3.5x3.5. The dull finish grabs more gradually provided a ball path that looks more like that of a old-fashioned curve (I think they now call it a banana). the 4.5x4.5 provides more length because there is less flare and it provides less backend and less overall hook, again because of the low flare drilling (except for Morich's special cores, of course..

For polished balls (be they pearls, solids, particle pearls or whatever)  the 3.5x3.5 should be snappier, because when they finish skidding, that 3.5", maximum flare drilling will allow the maximum rection in the backend. It will look more like what they now call a hockey stick backend.

These are "as far as I know".
