If your biggest issue is polished and pearlized stuff flying on the backend, then this sounds more like a surface prep issue. What about maybe taking a weaker ball and bringing the ball to 4000 no polish or something like that, in order to get it to read a bit earlier and be smoother in the back.
On a bit of a side note from the suggestion, i'm just curious why you call this "a left-handed drill?" Is it simply because you're going to put the pin cg and mb on the "left" side of the ball? Isn't really practical to just do this, as you haven't mentioned your PAP, revs, ball speed, or anything like that. The hole fact is you are already having issues with the ball hooking too hard or too much in the back and then want to drill it even weaker to make it go longer? Just curious.
