Hi Scott,
As a CC owner, you can have 10 free and 10 premium (pay for) tournaments running in your club at any one time. You never can tell what people prefer, so personally, I mix it up.
At any one time I have:
2 x18 holes
2 x 9 holes
2 x CTTH
And four 'tier specific' tournaments; one each for Hack, amateur, Pro and Tour Pro and higher. You kind of have to police the tour specific tournaments and make it clear to members that they should only play tier specific tournaments for the tier they're at the time. That way, members are able to compete against similarly skilled players and stand a chance of winning something.
I have the same tournie types for free and premium and I charge only 10 credits for the premiums, so that it's not expensive for members to take part, but they can still win a decent amount.
OK, so I've got 240 members, but taken on % terms, I get a good response rate.
By missing it up you give something for everyone.
Hope that helps
Regards
Andy
