Deermaster1,
Dont worry about how tough these old Bears are, I killed a nice little freezer buck on opening day back in September with a 1965 Kodiak, I bought from bowdoc.
I am currently shooting/hunting (in 15 degree weather) with a 1971 Super Kodiak and I own and shoot/hunt with a 1952 Kodiak Static Tip recurve. All these bows are 50# to 53# at 28" and all are all great shooters.
Bear bows are not noted as speed demons, but I'd bet they are comparable to most of the production bows and many of the semi-custom bows offered today. They are slower than some of the bows designed with speed as the main criteria, but they are rugged and dependable, you can bet on that!
I think the limb designs that old Fred and co, used are built to be stable and rugged, more forgiving of shooting errors (like the kind you have when Mr. Big is standing at 10 yards!).
Great bows!
imho,
Harry.
