Everyone here is giving good advise. If you're used to shooting 62#, I'd opt for the 60# Dually. Especially in cold weather, with heavy clothes on. This may give you an idea of how hard the Pat Duallys hit. I shot mine for 3D at the end of last summer (getting ready for fall). You never heard so much complaining about pulling arrows, and I have mine set at 57#. These things hit like a truck. IMO, 70# would be overkill, and not necessary.
