I just got a 66"whip and am very impessed with the performance I pull about30.5" down from 31" I changed to more of a low wrist. I bought it used, I'm thinking seriously ordering one in two piece with phenolic or equivalent in the riser section to raise the mass to something that's a little more stable weight wise. I think the two piece would be very advantageous to back pack hunting, no tools needed for disassembly and the two pieces would go in my pack well I think. I've hunted with my 64" from a treestand with no problems, don't think an extra inch on each end will matter for that. Used the 66" this year from Barronette blind for turkey with no problems either.
