The 1.10 and 2.20 BI tourneys are within your BR guidelines, so I definitely think you should play in those. I think you should stick with your BR and not play anything larger. Altogether if it works with your schedule you would have a shot in 12 events, which is pretty good. They are long tournaments, so it might get somewhat draining to play in more.

Since I have a flat 5% BI rule, I thought I had a large enough BI to register for all the 1.10 and 2.20 PM events, so I signed up for all of them. Now I just noticed that they are all re-entry and didn't factor that in. I know I really shouldn't play in them now, but I can't bring myself to unregister!!
