I have a 2005 Slayr SE, with magnum limbs marked 4-H, and "B" Nitrous cams with "H" marked X system shoot through system...The bow maxes out at close to 70# draw, at 28"...The A-T-A is close to specs, but the brace height is under the factory specs for the 2005 Slayr's...Factory specs per Martin's website say 7", but mine is approx. 6 5/8"....Also, the modules are "H", for high let-off, which is supposed to be 75%...I am shooting this bow at approx. 63# @ 28", and the holding weight is between 22# and 23#...As a finger shooter, this is O.K. with Me, but it seems that the bow is out of specs or something....I was told that the bow had 45# to 60# limbs on it, and that, along with the brace height being too low, and the let-off being light, I am wondering if something has been changed to have the bow set-up like this...The bow shoots very nice, except for the noise from the X-system ,(is there any good way to get this bow quieter??) and I love it, I just want to make sure that something isnt out of adjustment...I have heard of twisting up/down of the cables and strings to change draw weight and draw length, but changing let-off is new to Me......What say all of You fellow Martin Guru's??...Any help will be appreciated...Thanks in advance, and Take Care...Harperman
