I was shooting EFA's before.

Thanks for all the advice guys, I'll take the bow in on Saturday and report back.

i think its in your head dan, but i'll tell you something you didn't hear from me. not all modulesshoot equally. for instance a bow may shoot and tune better w/ 28.5" modules than it does w/ 27.5" modules. as a matter of fact i got some custom string lengths from a fellow who's top 5 in the world - pro class of asa - to deal w/ this issue last week. this was not regarding a bowtech, but the conversation was very interesting none the less.

This is so very very true. There is an optimum cam rotation for any bow, and a different cam for each DL really is optimum for performance, but most manufacturers (except Mathews) have pulled away from this now because it is a PITA for a dealer to stock lots of cams instead of just mods. It is a convenience thing..................

i appreciate you getting my back on that rickjames - i wasn't sure how it would go over - still am not really - but thanks.

also, weren't you gonna send me some cable lengths?

This goes with what gibblet is saying.

This is an honest question: Aren't bows usually manufactured with a certain cam length being optimal? Or, are do you think that even between 2 bows of the same manufacturer and model this could also be true?

Even if the manufacturerdoes not post that they do so.It would be difficult to manufacturer and have the same characteristics with all cam modules.

As a species we think about everything way too much.

dave, there are guys out there that shoot for companies that avoid certain modules on certain bows. they may start w/ a longer one than they need for that reason - and then get a string, for instance lets say a 102" string built at 100", and knock an inch off the cable, and get a bow w/ 3/4" extra brace pulling a few more pounds - and the right drawlength for them. they figure thisstuff out - i don't. this kind of thing is why a good # of folks shoot single cams.

That's interesting that they do that. I guess though if the cam gives them the performance they want by doing that it's a good thing.

its weird - the better folks shoot - the more manufacturers specs go right out the window. some of these guys have a lot more time to figure this stuff out than i do - and resources - to really find a bows sweet spot and have it fit them and give them what they need at the same time.

Yeah, have been working on the fita/field bow and haven't touched the slayer for a week or so. Will get them out tonight..........

Yes. Bows are typically manufactured for a certain amount of cam rotation to produce the maximum amount ofefficiency, this amount of cam rotation will usually be specific to a certain draw length. When you stray from that and compensate with modules instead of remapping an entire cam profile proportionally for every draw length that bow is sold in, you will lose efficiency. Will the average shooter ever see this or care? Probably not, but put a super short draw length archer on a cam that is now underrotated, and they aren't getting the maximum amount of energy that a specific cam could make for them if the rotation was specific for their draw length.

A perfect example of this is the mini binary or whatever you call it for Bowtech's Equalizer. This cam is specific for this bow (and the constitution) because that cam is mapped exclusively for a certain amount of cam rotation that is specific to short draw archers, or average draw archers with super long ATA bows........(both short draw and long ata have similar rotation characteristics). That is why the Equalizerat say 27" with the same amount of brace height and limb preload is so much faster than say an Allegiance at 27". It's cam profile has beenoptimized specifically for those shorter DL's. Great move on Bowtech's part, now they have one of the most efficient bows out there specific to short DL archers. Martin addresses this by offering A,B, and C sized nitrous cams so just about any bow can have an optimum cam rotation that is pretty close toperfect for just about 9" of draw length range, (each cam has 3" of adjustment on it). Mathews just doesn't even bother and makes a cam that is exclusive for each draw length because that is the best way to squeeze every ounce of efficiency out of the cam for each draw length, even though it is an inconvenience to consumers and dealers to have a specific cam for DL adjustments.

Heh.........so very true. [8D]

For shorter draw lengths I definitely can see the benefit in adjusting the string and cable length to allow the cams to rotate properly. I've always woundered how the effect is for longer draw lengths like mine? I know people talk about increased speed and such. Is this due to rotating the cams ever further over than a shorter draw length shooter? Or, is the mountain longer and then the valley steeper?

Thanks for the info guys.
