I have a friend who is a very low speed high rev player. Probably 16 mph off his hand and 400 RPM with very high axis rotation, and about average tilt.
Most of the equipment he uses is of the low hook variety, such as the Track 300 series, etc. Almost all his drillings are 5-1/2 to 6 Pin to PaP which usually puts the pin above his middle finger (Right handed).
He is going to Nationals, and wants something a little tamer for team. I suggested the Hammer Arson low flare.
My question is, would putting a 6 inch Pin-to-PAP drilling on such a tame ball (Arson low flare), produce an overall weaker reaction than say a 300c with the same drilling, or by the time you get to 5-1/2 or 6 inches, you pretty much have very little flare on either ball, and it is all surface that dictates motion?
Thanks in advance,

Try a 2 inch pin to pap on aggressive cover symmetric core combo. It will give him a sooner and smoother roll for fresh lanes. I have a few balls with 3k surface drilled like this and it definitely helps the over under seen on tougher patterns. Just a layout to consider.

+1 to this. For higher rev bowlers, this drilling should be tried for flatter shots. At least experiment with it.

+1 to this. For higher rev bowlers, with sufficient ball speed, this drilling should be tried for flatter shots. At least experiment with it.
Minor addition.

2 inch pins are awesome for taming over under. Surface is paramount, though. I've had to work the surface on my Grip-It to get the reaction I wanted. OOB (4000) was too much too early. I had to go 1000 with polish on top. Now it's a killer.

Thanks for the replies, although nobody has really answered the question, I still appreciate the advice.
Why "Sufficient ball speed", will a short P2P result in a ball that will roll out, or lose all tilt quicker?
-
Flare is dictated by rev rate NOTHING else...so as the diff increases so does the flare potential as does rev rate...if his rev rate is 400, I wouldn't not go lower than 5.5" from pap...you can possibly add a weight hole to open up flares down lane but if he is looking for 'tamer' but more just look for a stronger cover...say IQ tour type

Without the right ball speed for that pin-PAP, yes, the ball will roll too early, hit weakly, at best, hit sadly, at worst. Been there, done that. I'm rev dominant and have learned that, for aa symmetric core, if 2"pin-PAP work for the rev matched, I need to go to the opposite end of the pin-PAP spectrum, 5.5" to get the same flare/differential. this also increase the RG, to get more length. a 2" pin-PAP reduces/lowers the RG for an early rol to control the hook.

How about a Break Down? The ball is super smooth off the dry and isn't jumpy. Very drill and bowling style friendly. No need to adjust layouts on it either to control flare. I've had a few guys throw it who are heavy handed and at best I see 3.5" of flare. Give it a try!

I would tinker with surfaces before I went with niche 2 inch pin to pap layouts, that for the most part, hit like dog shit, but thats just me.

I have 450-475 Rev and 17.5 mph per the monitor. So I am borderline Rev dominant and the 2 inch works well for me. I also follow the 2 inch with a 5.5 inch when I have to migrate left. To each their own.

The real answer here is you aren't going to be able to do enough with the ball. Slow ball speed, a rev rate of 400 and high axis rotation is a bad combination, especially when you want a tamer reaction on more difficult conditions.
It's cool to have a car that will go 0-60 in 4 seconds, but sometimes you have to lift off the skinny pedal to turn a corner.
Sometimes a bowler has to tone things down a bit to get the reaction they desire.

If you want low flare pin toward the track.The 2 inch pin with low ball speed and lots of dry=ball that pukes.Early roll used up for the backend.A friend of mine bought the new low flare hammer its not a dry lane ball by no means.Just look at the core plus the aggressive cover.Don't understand why its for dry.Get a Tropical breeze and go 5 1/2 to 6 inch pin.should be fine for low flare.

Nationals isn't exactly low volume.
-
It's low ratio
-
I agree rico, it is a low ratio. For me, 7 degrees of tilt, high track slightly Rev dominant, the short pin gets me out of trouble on these types of patterns. I also said to each their own as well. The longer pin layout would be way to strong off the spot for me. While the short pin will allow me to stay right longer and not get into big 4 territory.

I went over to AMF to try and take his bowling measurements last night. Musing my iPhone with slo-mo isn't exactly CATS, but it's not too bad.
Rev rate 360-370 rpm
Speed 17-17.5 off his hand
Tilt - track diameter 12.5" = 5 degrees
Axis rotation 75-80 degrees
So he's slightly rev dominant, but has less tilt than I thought. Another important thing is his PAP is shorter than the last time I measured it. He was 5-1/4 over, now he's 4-1/2. So his longer drillings are actually shorter, if that makes sense. I've been reading up on the subject and it looks like PAP values can change with different cores, by a little bit, so I'm not too surprised by the change in value. Particularly since I was measuring off his 300C solid which is a high diff ball 0.055.
