Let me first say that I am new to archery and I recently aquired a Bear Alaskan compound bow. Can anyone give me some information on this bow, I cannot find much on the internet. Is this considered a "low quality" bow? Is it an older bow? The string or cable is frayed, if I were to replace it what length would I need to get and how hard is it to do on my own or would I need to take it to a professional? Any help would be greatly appreciated.
