There is not a doubt in my mind that the dual cam system is better all round than solo cam. I've only been shooting these crazy things for 30 years. I get at least one new bow every year. Been shooting solo cams since 1997. Duallies before that. Now I am back to a dual cam---finally. Level nock travel is not an issue. Neithr is cam-lean which causes sideways oscillation of the string. The string is parallel with the riser and not angled across it top to bottom. With the improvements in string material over the last 5 years the issue of cams constantly going out of sync is gone (assuming you put good rigging on the bow). Smoother draw, more quiet, faster.

Now, if only someone would do away with that stupid cable guard that pulls everything to the side, creating torque on the limbs and wheels. Oh, I forgot. Take a look at the Martin X-System (shoot through cable system). I got a new Shadowcat coming. Can't wait.
