what exactly does a pinaxis drilling accomplish in terms of shape, length, reaction, adn everything else? also what kinds of balls is it good to use on. and what are the proper specs for this layout? pinlength and tw?

Pin axis is meant to create the earliest, smoothest reaction possible. Since the pin does not have to migrate to the axis point, the ball is already at its final rolling position as soon as it's off your hand. This is why it eliminates flare. It's good for taming extremely snappy, flying backends for some bowlers.

As Dan Belcher said in the previous post a pin axis drilling tames the reaction of the ball down to the bare minimum. To my knowledge you can do this with any bowling ball, but i would personally go with a pearl. However i'm pretty sure you're going to need to have a pin out about 4-5 inches (depending on your PAP) as your going to want to put the CG in the center of your grip so that you wont have any finger/thumb or side weight in the ball. In respect of top weight i would go with a normal amount nothing to OTT, about 2 3/4 - 3 oz's.

I have heard that it's better to place the pin 1" from pap instead of doing a full pin axis layout. I guess this allows for some track flare but will achieve the same type of reaction which is roll!

By pushing the pin 1" away from the VAL/PAP back towards the grip center you're making sure that bowlers that occasionally spin the ball won't end up with a top spinning down the lane. It also helps prevent reverse flaring?

I just recently saw a pin on axis drilling (he used that columbia heavy oiler, Resurgence I think). it was pin about 1" from PAP, and the CG pointed towards hsi grip center. He launched it down lane and it was one of the smoothest arcs I've ever seen. I'm very curious to try this drilling out for drier backends/smoothing out reactions.

I have found that this layout does seem to work best with pearl coverstocks-either symm. or assym.. I have tried it on solid/ symmetrical but the ball seems to lose steam by the time it hits the pins (on dirt).
My favorite layout for over/under conditions-
Epic Quest- wanted a strong core/cover combo to help retain some hitting power
Pin to PAP- 1"
MB above thumb towards track- to help smooth out rxn.
Pin buffer of 3/4"
Makes the ball roll very predictable
Hope this helps,
