3.31's and 33's feedback?

Anyone running 33's with 3.31 gears? I am in the process of finishing my CJ7 this summer and just wanted some feedback on this combo before I button up the axles. The CJ has a 258, I will be swapping in a T18, it has stock height springs and a 1"BL. I need it to be useable offroad (I have the TJ for serious trail duty), pull a small trailer to haul firewood occasionally, and I need to be able to run up to 70mph without making screaming the inline.
