I just started 4 tabling (full). I play 25 NL. I think alot of it has to do with you standard of play. If you have a set strategy and have discipline to play certain hands you can go 4 tables +. If you are going to sit there and play 4 draw hands at once then obviously it will be difficult. If Gabe was multitabling yesterday like im sure he was, you would notice all his hands were somewhat standard PF play which is easier to play when you multitable. If you are playing all these crazy hands from the blinds, suited Aces, connectors and all that jazz its going to overwhelm you if your not used to it. It takes some getting used to. 6 max could be even more difficult because you can loosen up a little with your starting hand requirements. GL.
