yeah goose on here is runnin ifs with 33s locked and it goes pretty damn good.
skill carries you a long way. I'm locked on 35"s, and I'm really happy with how my truck preforms. I'll do a SA eventually, but that isn't a top priority. You'll actually develop a lot of skills with IFS, it forces you to be more technical, and choose your routes more carefully. In the long run, I think it can make you a better wheeler.
