Unless you get inventive with the pin placement, putting the pin further than 6 3/8 or 6 1/2 from your PAP will be in your track, pretty much eliminating all flare, making the core irrelevant.  I guess if you put the pin muck lower (even with your grip center or thumb), you could get the pin real far away from your PAP, but I don't know how that would roll.

For a tweener, even a power tweener, 6" is pretty weak.  I think you'd be better off learning different techniques for dealing with drying lanes.  Loft, floating the ball through the heads, seriously reducing your rev rate, changing your axis or tilt...

Thanks! I can back my hand out of the ball but I loose cary so I just wanted to see what a longer pin to pap would do. I have a Chery Vibe with a 6 inch pin and I feel it still makes a fairly strong move for me. I was looking at the Rayzr, but the no core aspect kinda make me think its going to leave alot of ten pins on pretty burnt out lanes with some carrydown.
