  1. So RG and Diff both make a difference on how early a ball picks up? I have always heard it explained that RG is the number that tells you how long it takes to pick up and Diff is the number that tells you how many boards it’s going to hook. This is the first time I’ve heard someone say high diff makes it read earlier

  2. Just wondering but II have a med to low track with around a 350rpm rev rate and around 14-15 mph ball speed. What type of specs should i be looking for in bowling balls? I’ve noticed shiny or pearl asyms and alot of surface on these balls seem to roll out on me.
