I find press easier, because at least you can keep yourself involved throughout the game. And it's quite easy to manage communication in 5 min phases with building downtimes etc. Usually doesn't take that much longer then GB either.
RR sounds like a nice idea, but I doubt it'll have much of a high-impact. Basically RR will be a replacement for bet-sizes, you might have some people with low points and reliable record, but those are quite rare. So if you set RR to high you just end up with very few people, same like if you set bet sizes above a 100

I don't really think it'll be all that useful, but who knows. Main thing that's gotta change is get people to realize how much more fun Live Press is and stop playing GB always..
Maybe some sort of live-league or something, or perhaps pay-out double the points for live games to give more people an incentive to play them.
