For all those who are looking for a well padded gig bag, I just bought a Gator G-PG ACOUSTIC for my 716, it has a semi-rigid structure (as mono m80), lots of pocket, nice neck holder, etc. etc. Not so expensive as the Mono, but equally well made bag (I've also had a Mono and RB for my acoustics).
This gig bag fits well the Grand Symphony shape (as listed in a compatibility reference list on gator website), less tighter on the widest part of the guitar than the taylor hard bag (I had the chance to compare them side by side in the store).
