RE: AMS reel?
AMS is a great reel. Bullet proof as fish says.
Look at it this way, approximately $70 for the AMS that mounts to the quiver/sight bushings, tie on an arrow with safety slide or rings and you're ready to go.
Or, you can buy a spincast reel for $30 to $40, plus a good quality reel seat for $20, replace the line for another $10, tie on an arrow and be ready to go. Forget to push the release button, lose the $10 (or more)arrow, retie, curseand repeat.
That being said, I use a spincast set-up. It's how I started and I just can't seem to break the habit. I know it has cost me much more in the long run. Most of the serious tournament shooters use a spincast set-up of some kind. But if you're not planning on becoming a competetive tourney shooter any time soon, save yourself some hassle and go with the AMS.
Good luck and good fishing.
