Kevin,
If i remember correctly, the bear flare was made in 1988-89, it had 50% letoff.
I think it was around 44" in length, as far as draw weight , you could get it in 45-60 and 55-70.
couldn't tell you the speed thing, but it was decent for back then.
The bow should have a spec. tag on the bottom limb, for string length and poundage, draw length.
If the string looks fuzzy or frayed, i would have a bow shop check it over, also check for cracks in the limbs.
