Sir, here are some things to think on....
I personally believe that it's about "being out there," and not necessarily the "tool" that one uses. That being stated, I use one of my recurves 90% of the time. The other 10% is during the late season, when I have not yet harvested a deer, & am looking for some fresh venison for the freezer. This happens frequently, since most of my bowhunting is done on the ground in public land, so I come home empty-handed way more often than not!
So, come the late season, & looking at an empty freezer, that's when I pull out my Xbow, or my .44 mag, one of my rifles (or shotguns,) or my flintlock, depending on when/where I'm hunting, and I take the first nice fat deer that I see.
But, I enjoy the experience & learn something new each time, regardless of the "tool" that I'm using. I started my son with trad bows many years ago. He's now 28 yrs old, & has migrated to compounds & Xbows- that's ok, because he still enjoys spending just a few days a year hunting with "the old man," & as long as he does, I don't care what he hunts with. I even talk him into shooting the trad bows once in a while when he comes home to visit! So, maybe that ember that I'm trying to keep smoldering in him will turn into a flame someday...then again, maybe not, but if he still enjoys "being out there" after I'm long gone, I'll check that one in the "win" column!
Maybe it's too late to try yer buddy's lighter bow, then again, maybe not... the season runs long, & maybe you'd be ready to hunt with it in late season?
Or, maybe it's time to consider buying a lighter, much less expensive bow, (like a Galaxy Sage, for example,) so you can be ready if the same misfortune happens next year, & you'll have yer own rig to use...
I know there will come a time when I can't draw a bow...it will happen to each of us, and at the time decided by God.
But, then I'll use something else, because to me, it's all about "being out there." As long as I can "get out there," I'll "be out there!"
....just some food for thought....hope you recover soon!
