Points are not the deciding factor. I've played in games for hundreds of points with CDs and I've played in games for under 100

(Leagues/GR Challenge Games) which were great.
imho, if you're going to CD, you don't really care about points anyway, so unless the pot is over 100 (and even then) you'll have problems. Plus, not many people are going to want to play 100 point live gunboat game.
I'd suggest you play with people you know to be reliable players; that's really the only solution.
