My first compound was a Darton SL-50. It was an excellentbow back in 1980. Simple...no cams, just wheels. I seem to remember that it was set at 55 lbs. with a 50% let-off (which was about average at the time). I put a lot of meat in the freezer with it! I shoot a Trykon now (and before that an Ultratec), but my brother-in-law still shoots Darton products and swears by them!
