I agree, there is not enough of a variety of RG tourny's that interest me. I cannot birdie 7-9 holes in a 9 hole game which is what it takes to win against better legend players. The high stakes RG's should be much broader and be available in both tier and non tier platforms. I will not play the high stakes RG's because it is filled with superior talent and I just simply cannot compete on that level, not yet anyway.
It is a lot like playing poker, you can play poker at any level you want as long as you have the money, but if you don't want to go broke you don't promote yourself or buy into games you do not have a reasonable expectation of being successful in. 18 hole Rg's at high stakes should at least be offered as well as high stakes RG's in tier or group tier (pro-tour pro, master-tour master, etc) formats.
