Honestly, I find it harder to pull G in the T-34 than in the T-45. For me at least, the G-Suit really seems to help a lot. I had to hook at 4G in the -34, where I don't have to do anything in the -45 other than just fly.
note: I am an E2/C2 guy, so I don't do weps or ACM, so min radius turns are about the most sustained G I see.
I need to at least tense my legs at 4G, otherwise I start seeing stars. This is with the mask on.
