Hi folks. Pretty much just using carts now in my Fly and Invictus dd. But my question is I love my Hyper and would like to use carts in that also. I know I need to remove the stay up spring, but been told I might not get it back in if I need to. Has anyone done it and duz it run ok with carts as I've also read the give adjuster don't really work with carts. Any input would be great please.
