If the longer bow feels better to you, then IMO get it. I wouldn't worry all that much about the 4" differenceshooting out if a tree stand. Just make sure you practice out the stand at every imaginable angle.
FWIW, I also like the feel of a longer longbow. I don't think I'd ever purchase another less then 66".I actually, I don't even own any less then 66" anymore.Below is my Schulz which is 70", and I love it!
