it does exist in theory Bill Hall put me on to this method, He drilled on the PBA truck for 15 years.
You make a new centerline anywhere from 1/8 to over an 1 1/2 to the right on a right hander or vice versa on a lefty. It will take a few times to get it right, I had this for about 3 years.
Honestly got refitted the correct way and bowl better than ever, Jeff Walsh from K & K bowling services hooked me with my current grip and his co worker Sakae initally got me away from the CLT.
A T-grip is a T-Grip in no other terms, yes there all offset grips but they all equal a T-Grip just different spans and pitches.
Just try span and pitch changes and save yourself the hassle of having a cheese ball with plugging all over it.
