    three speed knocks at each end of the string are going gain you 6 to 8 feet per second

    I've got the timing gap on my cams right, but now my ATA is 33. and my weight is 67lbs. this is a 60lb bow.If I untwist the string to get my ATA right , my gap on my cams will decrease right??

    The originals come with speed nocks. Crimp two brass nocksets about 1" to 1 1/2" from the cams. Then shoot it over the chrono to see what you get. Play with the distance from the cam while shooting over the chrono. Might have to add a third nockset. As for the specs, add ten twists to the string and take about five twists out of each cable. This should drop the weight and shorten the brace height. You'll have to adjust the module to get back to the present draw length (maybe 1/2" longer). Don't forget to adjust the draw stop and STS. The cams will advance a little and actually smooth out the draw cycle, too. Let us know how it goes.

    well I added the twists to the string and removed them from the cable. that definitely got my draw weight down, but it also dropped my ATA to less than 33".I also have a little bigger gap as far as cam timing.I would say it is a little more than 1/8"from string to post.should I try to get my ATA longer, and if I should, how would I do that. thanks alot fellas.

    well i rechecked my timing at full draw and I am about perfect. the top cam might be a skoshe advanced. but any twist of the cable will make it too much.my ATA is still 33.my brace is 7 1/4 and it maxes at 62 lbs.

    Thats close enough to spec to not make a difference mine is 33.75 ata 62 pounds and 7.25 bh but i think my string just stretched a little when i checked it when i first got it i was right on specs.
