Well I'll start..I understand not wanting to sink money in..I do! I started with a bottom end pro-line bow. BUT it was the current years model. By dating yourself back a decade or more you are missing out on the technology. Perhaps this is the technology that will make or break your decision to bow hunt into the future.

This isn't old school hit a haybale and a paper plate stuff. There is no reason that within a few practice sessions you and your son can't be shooting sub 5" groups at 20 yards. That is with modern equipment including a good Bow, release, sight, and peep sight and PROPERLY fitted arrows for your set-up.
