I bought one new in about 197? Early 70's late 60's anyway. I still have it. It shot pretty well for me, and your draw length is very close to mine. The grip is the most radical of any of my bows, but the grip seems to be very repeatable.
For a brief period of insanity I shot a compound bow in a league. One night just for kicks some of us brought old recurves and messed around with them. I did not have tuned arrows for it, and the nock was not quite right, but at 20 yards my first two arrows were in the kill zone, and within a couple of inches of each other. The guy next to me asked "how did you do that?"-I replied "don't Know - just did it". I had not shot instinctive for a couple of years at least.
In retrospect, I think that was the night that I started rethinking about going back to recurves.
My brother in law bought a 55# SM48" at the same time, but sold his a few years ago. Do they just make 45# SM's now?
