I too wanted to go to a 60 lb. bow but opted for yet another 70 lb. bow. Part of my reasoning was because the Bowtechs I looked at all maxed out at peak weight......maybe one lb. more. My new Patriot maxes out at 70.7 lbs. and the 60 lb. model maxed out at 61. I feel way more comfortable at 65-67 lbs. with this bow at around 70-73% letoff. If I adjust it to 65% there was no valley whatsoever and I have been guilty of creeping now and again.
