Yeah, even though I'm getting up there in years (54 soon) and have had shoulder injuries, #65 is a good weight for me to pull. Don't know how much faster it really is than my 60 pounders, peaking at #61 or 62 though.
Ironically enough, both of the MQ1s I owned peaked at #66. The only thing is, the first one was a 60-70 bow, and the last one was a 50-60.
