I wonder if the hooking issues aren't related to ball speed. Is that relatively consistent too?
I would also try to button down your accuracy. 2-3 boards at my center is a "big miss" I normally have one board either way or I'm in trouble, either no hook or too much hook...
The etiquette thing is somthing most of us deal with on a weekly basis...I just figure out who really doesn't have it, then make sure I either wait for them to be done, or I go up there and just let them go first no matter what...
