Default RE: Bowtechs new cam system

In technical estimation (not just the usual blowing biased smoke please) what does this symetrical system have that asymetrical hybrid systems, (which BTW have great nock travel AND drawlength adjustments in 1/2 increments via modules) do not have? To date no-one has been able to answer this question with an intelligent and/or non-biased response on this or any of the boards....

Asymetrical hybrids have a 3 track on the bottom cam and a 2 track and yoke on top instead of another 3 track on top as this system exhibits. That's the obvious physical difference of course---what I'm looking for is hands-on comparable tech analysis from anyone (other than Bowtechs staff shooters, fantical fans, or dealers) who has tested this system thoroughly and put one on an apple machine or crankboard side by side with other hybrids to compare nock travel, limbtip travel, and other static measurements, or, better yet, shot them both side by side with NO BIAS, AT DISTANCE out of comparable ATA and brace height bows, either with a hooter shooter, or freehanded.

Reason I ask is that from my own technical knowledge of current cam designs, once you factor the berger hole being higher than the centerline of the bow, much like a true twin I would then venture that the symmetrical hybrid cams' nock travel would thus start out high also as well. Twin cam designer Lloyd Napier recently built an asymetrical twin cam system with one cam of slightly larger radius to compensate for this phenomenon and thus incorporate true straight and level nock travel. But it cannot be done on cam systems that are perfectly symetrical due to design.

Asymetrical hybrid systems also allow manufacturers to "build in" a wide timing range via modules for an easily-adjustable dynamic balance range allotment which promotes improved holding/ aiming qualities while still maintaining the excellent nock travel at all drawlengths. Standard symetrical twins can also achieve this to an extent with a preferred cable twist here or there but unfortunately CANNOT develop perfect nock travel at the same time IF they're perfectly symetrical, as this system is stated to be. If the symetrical hybrid is in fact perfectly symetrical and self centering and does not allow for this individual dynamic balance adjustment due to it's design as implied, (in other words if one can spin the power cables 25 twists as bowtech staff have stated without affecting the nocking point height/limbtip travel /dynamic balance ) how can individualized dynamic balance be acheived then? Dynamic balance is very important also to overall shootability and so this question is my most prevalent of this design.

I recently shot the Equalizer and it is fast, yes, but speed honestly means little to me, been there, done that, one always gives to get there. The speed increase here is due to the early peak and strong force draw curve of this system, plus the fact that it has no yoke which also slows a bow down slightly. Yokes with symmetrical systems however compensate for any speed loss with being able to straighten the string/limb/cam alignment with an outrigger buss twist on one side or the other should one experience any cam lean-- something one cannot do with this new system-- no matter how close to the cam the cables are attached, it will still exhibit some side-pull--- whether enough to wear bushings quickly or affect accuracy remains to be seen of course---it stacks heavy on the front end of the draw and then settles down, and altho I wouldn't call it "smooth" as others have done, I would say it is very "manageable". On the individual bow I shot along with others in the same shop there was some cam lean , at least as much as many solocams I've tested previously with a laser. As stated and to be more than fair, whether it becomes an issue or not will be determined over time and as an increased number of draw cycles are exhibited. We’ll see.

I will be further testing this design in the coming weeks as I am very interested in it's overall technical stature as opposed to other current hybrid designs, as stated above. Any true technical (and non-biased) input from anyone will of course be appreciated.

Basically, I like to know how things "tick"-- I for one don't believe everything I read or fall for the “I’ve got one and it’s great” hype until I know myself it is warranted--- I've seen that stuff far too many times, from far too many manufacturers and their Staff/ fans.... Like I said, I shot the bow myself, so I know how it feels. It’s a solid bow--- the cam system needs a closer look IMHO. Still has the same Gordon limbs, same riser, same everything most other Bowtechs have. Hype from staff and fans carries a lot of weight tho, and they will sell boatloads of them.

So the single lingering question remains---what makes this design better than any of the other current asymeterical hybrid systems? Anyone?

Thanks much! Pinwheel 12
