For me, as tournaments go, I have been more successful in RG's for my tier (Tour Pro). I've only entered 4-5 so far, but in all but one of them I have been in the money. Now, that's not so say that I've "won". In one, I made my credits back and in 3 others I've made some of my credits back. For me, starting out, getting anything back is a plus.
I only enter RG's for my tier. I'm not going to shoot in the low-60's or sub-60 so why risk credits in an open tournament against much better players?
Regular tournaments are bad enough. The other day I shot one of my best rounds and was 24th (I don't remember the course). By week's end I was out of the money. Whether you're competing against legitimate good players or cheaters, there's no reward for someone like me.
However, I am attracted to playing in RG's for my tier and I would think the majority of players on my level would feel the same way. I don't think I can actually get first place, but I do believe I have a very good chance at getting all my entry fee back, which leads me to believe I also have a chance at finishing better than that and actually making some credits. But only in RG's for my tier. Anything else and I'm just throwing away credits.
