I think i'm on about 6 now. I dont play them all seriously though..
I usually play the paradise ones seriously as well as large $$$ freerolls... generally with the $50/1000 entrants ones, I go aggressive early and if i win a lot i start waiting for good cards and build it up.. did it last nite and finished 6th... took till 5am from 1am though.. bit gutted lol! Only got $2
More freerolls = more experience. Note how you play and how you finish. As in aggressive/loose/tight etc.. and purposly change from tourny to tourny to see how it goes.. The more aggressive you are the more bad beats your gna get,, remember that! saved me a few times.. and killed me :s
