You resentful because it's a lot of work to build a rig and you are having to do it twice. Tubbing is the hardest part of it so of course your second guessing whether to stick with 35's.

I was on real 33's(295/70/17) for about a year. With what and how I wheel they simply weren't the tire for me. I was able to do some hard trails with them but 35's would make it so much easier. So I stepped it up. When I kill these 35's I'll be going up to 38's. It will be a metric shit ton of work to do it right. For me that work is worth it to have the extra clearance and ability to more easily roll over big obstacles.

Sit down with a few beers and ask yourself how hard you want to push the wheeling. If you don't have plans to run things that are considered stupid in IFS rigs 33's will be fine. If you want to join the body and brain damaged guys better get out the grinder and welder. lol
