If I go up from this one 2 feet past my roof line do you guys think it’ll pull well?

Maybe. But if you are still using single wall it will be to close to your roof causing yet another fire hazard.

Double wall is a lot of money so I’ll have to stick with single wall and keep it supported away from my roof. And the 90 degree bend will move it farther away from my roof.

Sounds penny-wise and pound foolish. It's clear you're going to do as you wish, disregarding a lot of safety advice, code and guidance.There are ice shacks with better safety practices.
I don't see a reason to keep this thread going. Best of luck.
