You don't need to stretch for 470 or smaller with 72mm tails.

The longer tail throws the COG off. I installed a full size tail servo on mine when I had it and that helped a bit, but not all the way. In my opinion the COG only matters if you piro a lot. If you don't, in normal flight it won't matter.
