I've only owned one single cam a PSE Durango. All my other bows have been duel cam. I never could shoot or tweek the Durango with the same accuracy as my duel cams. Now! It might be that particular bow but thats my only reference to single cams. I still use it as my back-up bow but I never really had confidence in it for target shooting. I went back to a duel cam with a Merlin Max and there's no comparision. I've have the Max shooting 3" groups @ 40 yds. and my scores have increased. It's the best I have ever shot. It also has a draw stop built into the cam which gives it a solid wall. Most likely I'll order another duel cam from Merlin this year. With all I 've read about the knock travel on the single cams I'll stay with the duel cams. I just seem to understand the mechanics of them better then the single cams.JERRY
