Heres my take on your question. I bought this ball for drier lanes. OOB it checks up to early, tried it on a drier lane the first night and went half way and started checking, thought ok, maybe this is stronger than I thought.
Went home and put it on the spinner, took it to 2000 then hit it with some of Beans polish. Now I can play on multiple lane condition, light oiled lanes or broken down lanes that are hard to control it is great now. putting the polish on it made it a whole new ball in my opinion. So if you are buying it for drier over reacting lanes then take it a little higher in grit and throw a good polish on it and you will be fine.
Note: When polishing this ball it seems like it isn't polishing, just looking like a sheen finish, but from what i have found it still works as though you have a good polish on it. 2 to 3 coats and it will starts mirroring up.
