C11hd vs Meade 12" f/8

I have had my C11 next to a 12 on two occasions and saw nothing in the 12 that I could not see just as well in my C11. In fact the last time I did that comparison the C11 beat the 12 pretty badly, but only because the 11 was able to adjust to the dropping temps better that night. I believe the mirrors in the Meade scopes are much thicker than those in the Celestron, which causes them to adjust to temperature changes slower.
I am sure there are some faint galaxies or planetary nebula that a 12 could see that the 11 could not, but I will bet that list is pretty small.
As far as the HD vs ACF goes, the HD approach is better according to everything I have read. Apparently you have to have a corrector lens, as celestron used, to properly correct for the various aberrations in an SCT. Just reshaping the secondary is not enough.

I owned both C11's and M12's and I prefer the views through the Meade. But YMMV.

I can see the f/8 being a bit heavier with new focuser, but not 20 lbs more.
