Thanks, everyone:
After too many years of trying, buying and using, there were very few of established quality, regardless of basic design, that were not ok. I have enough bows to equip a small club, but haven't had a Bear since the 1960's. For nostalgia, they fascinate me. I had an unusually close relationship with the Bear Organization in the mid-60's, but all my contacts have departed for a better place.
The only issue that creates frustration for me is an inherent design or materials flaw that makes a particular model more or less of a consensus "dog".
I am searching for the best "wrung-out" model. I would like to avoid an otherwise well shooting year/model that was improved next year.
So for my next purchase, it is mostly a matter of proven design than minor personal shooting characteristics. Tx.
