I don't like the split idea much. If you're going to do it, having the two levels is much better than individual pairings, but I don't think it accomplishes much. I'm at 5/10 now but I can certainly use critique from a 1/2 player, even if he or she has just started. It's always nice to have someone who's so focused on the fundamentals. I mean, sure, everyone wants a review where the focus is on third-level thinking and value betting your opponent, etc etc. But the basic stuff is crucial too, and easy to take for granted if you're 4-tabling on autopilot.
