Rags,
At some point in time, you've got to develop some revs, some "hand".
The Rush is a strongish ball for medium to medium-heavy oil patterns. Whether it needs dry-ish backend for either depends ont he the combination of your "hand"/"revs" and the drilling.
I hate to harp but 10:30 and 1:30 drillings don't tell us crap about the ball's drillings, UNTIL we know where you placed the pin AND the pin-CG distance (that last one affects flare capability).
If you are a stroker, then I can see medium-light to medium (AGAIN, depending on the drilling and the carrydown). I have a vaguely similar Remedy that I can use on medium to medium heavy; it has a short-ish pin of about 1.5" from pin to CG, drillined pin under ring finger (abour 4" from PAP). With a polish, it can skid. With an 800-100 grit matte finish it can handle carrydown on medium-heavy oil.
Try modifying the cover on one of yours with a grey or a green nylon pad. There should be a significant cover/surface difference in order to differentiate the two. The drilling (1:30 vs 10:30) is not enough, in my humble opinion. That difference is good for intense tournament competition. In leagues and local tournaments, you really need a surface difference also.
FYI Welcome back. Glad to see you posting again!!
