These all look pretty fine, although I'm at the same place as you, I've just moved from FR to 6max. I've played 2500 hands there so far and am doing well. It's an interesting transition though, I've gone from being a nothingy multitabling profitable nit at FR to a semi-loose aggressive type. I'm personally finding 6max great fun, as there are less nits, and you have to learn to play poker at 6max, whereas there isn't that much poker necessary at low-stakes full ring.
