thats a common weight so the odds are in your favor already,,, tell your nephew to keep his hands off your gear,,,, I'd tell him for ya but he sounds alot bigger and stronger than me so I'll leave that up to you 8^)
oh also Ric was from Montana I think right? I'd do a search for any Montana Bowhunting forums and register to make a post asking about marriahs... the home states sometimes have the most owners but the word will be out there and I wouldn't be supprised if you got a whole bow for the price of the limbs.
