I think everyone should be overbowed
Hear me out. I have a bunch of bows these days. Most selfbows are 45-55lbs. I have a 50lb martin savannah (my first and favorite), a 58lb zipper, a 66lb black widow, an old 36lb colt recurve. Now, I shoot all these bows some of the time. I give the zipper the most attention. I shoot my savannah the best.
So here's my case. After I get done shooting my 66lb widow about 15-20 shots, I am done with that beast. I tend to short draw the bow in the stand so I have to have a clicker. And get tired easy. I have to use an extra thick tab, because the little D97 string seems to cut into my finger at full draw. Even though I shoot it well, and its a great bow, I would say I am overbowed. Good news is I always have a clean release with this bow.
But here's the beauty of it. After I get done shooting this bow, everything else seems effortless. I feel like I have complete control of my my martin. I come to full draw every time, conscience thought of my release. My bow hand is very loose, no torquing. Same with my zipper.
I don't know, maybe it makes me stronger. Maybe its making me more conscience of my form.
