1x2k, 2x1k would be good. So what if they take a week to fill. You can only play the weekly singleplays once during a week so it's the same.
I'd also like to see a lot more 500cr RG's and some of them be 9 holes. Then a mixture of 100/200/300s.
The 50cr RG's go down well also as the big boys tend to stay away from them and this gives others a chance to win something and get a bit of experience playing RG's but on a smaller budget.
BolloxInBruges: Maybe reducing the rake to 10%
And this is a great idea :)
