How "old" is your old bow? If it's several year sold....let him also shoot your current setup to see what's out there as far as technology, today.

First bow I shot was a Jennings Buckmaster. Not a bad bow, at all.....but worlds away from my current rig. If I were wanting to get into riding motorcycles....and all I had to see if I liked it or not was an old Norton......I don't know which way I'd lean! Put me on a modern Harley, though.....and I'd know real soon if it was for me, or not.
