I wonder what some of you do on Wolf or Cheetah or a tournament condition where the front part of the lane is high friction and blown up (approaching toast)........I really do.
Adjust.
I regularly see what you're describing. I generally move in to find head oil and hope I don't run out of room. Next step is to play with hand positions, maybe dumb down to a high RG weak resin, or as a last resort, my Storm urethane Polar Ice. This is 'normal' and to be expected.
But when it gets to the point of having to throw plastic up the back at 19-20 mph instead of my normal 17 mph release, it's really not bowling anymore. You know for certain when you're ball needs a resurface after the fun-and-games brickyard event.
There is dry, and then there is DRY.
