Wow. So little love for the SuperMag! But You have gotten good advice, I guess.
I bought a 45# Super mag brand new in the 1970’s. Then I went into the Army, got married, had kids, and didn’t have much time for bowhunting.
Around 1990, I joined an archery league and everyone was shooting these new contraptions. So I followed the herd and did the same. Then at the end of the season someone suggested a throwback night. A lot of guys joined in and brought their old recurves for a shoot.
I dug out the SuperMag. The first two arrows were in the kill zone, slightly high but a pretty good group at twenty yards. Somebody asked how I did that and I replied “ I don’t know, just shot it.” Then and there I realized what I had been missing.
Kinda went crazy buying new and used recurves, long bows. Somewhere along the way I sold the SM.
I don’t remember excessive noise or finger pinch, but it probably had some. But I remember it fondly as the bow that brought me back to my senses.
