Hey guys I'm working on my posture and sitting straighter. I have a aero t w/ adi 13 inch contoured backrest. I recently took out my 4 inch dump and changed it to 3 or so, this helped a lot. What do most quads use as dump? I feel like I am not sitting up straight and it affects my push and is uncomfortable. When I lean back against the backrest I feel as if the top of my body falls over the backrest.should I take out more dump? I was thinking about trying the adi backrest which is not contoured. What backrests do you guys reccomend for a c6 7 quad
