I have this mocked up in the Demon and it looks like QA-1 DD303 shocks will fit the best (9 3/4 compressed, 12 3/4 extended = 3" travel). The QA1 literature says the shocks can 7, 8, or 9" springs. Their cat shows for 2 1/2" ID springs they have 7" and 9", or 8" plated.

What are the pro / con of one length over another, as long as the coils are not close to binding?
