The cam 1/2 uses 2 cables and 1 string.

Wrong , 2 cabels , one string , only one of the cabels is split . The top wheel on all hybreds [except hoyts] Has a half round tract to it , while the string rides on a cam matched to the bottom cam .

I am not familiar enough with the Hoyt bows and take your word for it.
The Darton system, however uses only one cable, as I am looking at it right now in their 2004 catalog.

Straight from dartons tuning instructions , Bowstring , Power cabel , Control cabel . Not trying to be confrotational , just trying to relay info that is as close to fact as my biased opinions can be .

Damn picture making a fool out of me....like it takes a picture for that, I am good at that all on my own[8D]

ijimmy, is it possible what they are calling a power cable is really just 1/2 of their string? I just keep looking at the picture trying to figure it out. The reason I ask is because it only shows one yoke.
And BTW, which way are you biased?

I probably will just wind up confusing someone, but here is MY perspective on the Hoyt vs. Darton systems - Hoyt's Cam & 1/2 is a hybrid dual cam and the Darton/Merlin system is a hybrid single cam. Both are cabled the EXACT same way. However, the cable track on the "idler" of the Hoyt is cam shaped, where as the same track on the Darton/Merlin cam is round. The string track on both systems matches the shape of the lower cam. IMHO, the ATA should classify hybrids into two categories, the hybrid-dual and the hybrid-single. That could end some confusion and perhaps provide a little 'incentive' for the two camps to outdo the other in terms of cam performance.

Good anology Olink , the two systems are vastly diferant . Mlauber , the pictures dont do it justice , you got to hold one in your hands , and see where the cabels are tyed off on the cams .

mlaubner,
I believe you are only seeing one yoke because the control cable slaves the rotation of the bottom cam to the top cam, not to the limb. I will wait for an expert to step in here, but I believe this to be the case. I believe the power cable is the more traditional one, which is tied to the opposite limb. Again, expert insert correction here.

I expected that my statement would draw a response.
TFOX, yes I know what creep tuning is, though I don't bother. So it's a tuning option when two cams are present, not the cams themselves that are more forgiving. IMO, creeping is more prevalent with two cams than one due to a less definable (solid) wall. Some people shoot dual cam bows "out of the valley" for this very reason.
TFOX:
Why not in all hands?
TFOX:
A tuning option.
TFOX:
I feel this is more product of width of the valley, and percentage of let off. A narrow valley, with low let off, will have less transition when shot. Another tuning option on some cams, by design on others.
ijimmy:
I assume you meant "perceived" to be better.... You kinda lost me here. Do you mean to say you actually got tighter groups, shooting darts? Or it "appears" you got tighter groups, shooting darts?

A person needs decent, repeatable form to get consistent shot placement. This may be better achieved by some cams when a bow goes out of tune but, continuing to shoot an out of tune bow is not something smart archers do. BTW, I heard Mathews is coming out with an innovative variation of the hybrid cam. It's called the "inbred cam".
