The GF's Covert came with 2013 CTD shock and 34s and the performance has been good.
Initially I was sceptical about the need for a middle size fork (and she originally wished it had 36s) they seem to perform pretty well.
We set them up using the Fox App (sometimes it takes a few attempts to photo the sag correctly) and as said above I would probably have run them faster on the rebound.
It might be that she's lighter than a lot of the reviewers and obviously not as fast or big hitting as some(although she can hold her own on DH and jumps with most people) but they've not been blowing through travel.
I understand that they've got problems and have been changed for 2014, but I sort of agree with them about not needing hundreds of settings to fiddle with if the shock is initially set up right for rider and bike (which is what Specialized and Ohlins have said as well).
I'm sure there's better out there from other brands, but she's happy with them at the moment (and she's normally very fussy about her set up)
