Lots of stuff you can do to fit them yourself. If they're loose, put a piece of duct tape on the limb bed channels or the limb beds. That usually does the trick. Or, if they're really loose, sometimes a small felt pad 1/16 of an inch thick on top or bottom of the limbs near the butt and or on the butt themselves will tighten things up.
Bear has been makingTD limbs for about 50 years. A lot of different folks have been involved in the process. The limbs are close, but they're not all the same. Haven't found a set yet that I couldn't make work with any age riser. Just have to tinker a bit.
Good luck.
