-Travel distance is a big one.
-Next is time. Does the tournament start at 8:00 PM, it is 50 miles away, and will I not get home until 1:00 am?
-Race to what? This also has to do with time. Is it a race to 5 and 50 miles away and I will not get home until 2:00 am? (Prefer race to one or two for evening matches so I will get home at a reasonable hour.)
-Does the tournament ban the best players? I want to play the best players, watch them shoot, and learn from them. If the tournament bans the best players, I would be less likely to play there.
-Does the tournament ban certain play such as safeties/jumps/masse' shots? Not a biggie, but this will not help my game much. If a choice between a tournament which allows these things and one which does not, I will go to the one which allows more.
-Consistant written rules. Does the tournament change the rules each week depending on who shows up or who the TD is? If yes, probably won't play there until they get their act together.
