nice work.

consider playing 2 tables.
Easiest way to get comfortable doing this is to spend an hour 7-tabling play money. Then, drop down one level in stakes for the first session you play the extra table. There is a lot to be said for playing less rather than more tables - but I think that this only really starts to apply at >4 tables.

Get in IRC sometime and sweat someone playing 3-4 tables to get a further feel for it.
