My ZCRP is layed out just like IL_BOWLER & track is clipping the thumb hole. If i redrilled with pin,cg,+mb on right positive side will that help in lowering track?? thanks.

yes the PSA should be kicked to the right of the thumb the farther right you kick it the more aggresive the ball flips
eeeeeh... not exactly, high revs this guide should help you...

Actually, the further you kick the psa out, the earlier they hook, the flatter they are on the backend, and the more they suck . . I haven't seen a new Zone yet that rolled halfway decent at all if the psa was kicked out any further than 2 inches, and that's even pushing it a little.
You haven't seen my Vapor Zone then. Mine has the PSA kicked out almost to the VAL and it has a sharp move at the breakpoint with plenty of hit. I'll get a picture of it and post it. Same with my friends Strike Zone with the PSA on his axis.
EDIT: OK, here's a pic of my Vapor Zone. It was a left behind ball of Mikas from the Medford PBA stop. I just glued a slug in the Switch Grip sleeve and plugged the fingers. Not sure if the surface was tweaked any, but it looks like the box finish to me. Hooks a lot, but still has hit.

if the pin position is in a max leverage position, there is very little mass bias can do to alter the reaction, that is a big reason why you see "pro layouts" with a weaker pin position (neg of centerline) and a stronger mass bias position (45-75°) so the mass bias has a greater impact on shaping the ball path.
so looking at the layout on that vapor, it looks close to 1E on the brunswick sheet, which would put it close to 3&3/8" from PAP (Max Leverage).

The PSA(we are in a brunswick forum) is a just a fine tuning tool. I like the psa near or on the val, anything more than 4" from my axis has been a huge turd for me. They are just too uncontrollable.

Mass Bias near the thumb is not "least hook" !
Mass near VAL is not "most hook" !
See this is the kinda info that newbies read and then they get it all wrong from the start
Pin position determines flare ! ("Hook" if you will)
Mass Bias placement determines break point shape !
Most of this is over shadowed by coverstock prep !
