Move up or add table(s)?

[ScottTheFish]

I've been 2-tabling the 100NL 6max on Party/skins since about February, beating them at a pretty good rate. I'm confident I'm a winning player at that limit.

I have enough in the BR that I could comfortably play 200, but there are so few 6 max tables at that level, I wonder if it's worth it.

Would you recommend moving up or adding a third (and possibly 4th later) table at 100NL? At 3 tables I think I could play my normal game, At 4 6 max tables I'd prety much have to just nut peddle.

Whaddaya think?
