So far, so good. I played any/all 50/100 and 30/60 games on Full Tilt for 3.33 hours tonight, with good results. And more importanty, I was enjoying it.... The fast pace of multitabling and constantly feeling engaged in the action was a needed change of pace, I'm going to keep this up for awhile and see how it goes. There was even a stretch I had six 50/100 and two 30/60 games going, all being played from my laptop. Fun :)
Here was the end result of my grinding today:
Even though that shows the MT ratio as 5.20, I'm pretty sure a majority of the session I was on at least 6 tables, since the first hour or so there weren't nearly as many games going and I didn't initially decide to also pop into the two 30/60 games.
