xSTILLFLY: What kind of competitions/rewards?!
Most clubs have both free and for credit tournys plus alt-shot, match-play and specials for when the majors are on. Some clubs allow all members to start their own and some don't, I do. Personally I set the for credit tournys to the level where I get the most entries. It's no use charging 50 credit entry fees if nobody plays them. I also have comps for the different tiers to keep them involved which have balls as prizes, and I'm sure others do the same.
