I have a 10" f/6.3 SCT, the central obstruction is significantly larger than in a f/10 and that leads to lower contrast. (Though despite that, aperture wins, and a 8-10" SCT has that in spades.)
p.s. what kind of mount do you have for your SCT?
Fork. I have a wedge but I don't ever use it. Alignment of a wedge is as much of a PITA as a GEM and I don't do photography any longer.
