Droptines,

Just a suggestion...sounds like some string stretching occured after your LX was assembled and shipped. Try this: since you have already altered your cable length to get your cam in the position that you want, mark it with liquid whiteout on both sides of the limb. Then after relaxing the string and cable in a bow press, twist up/shorten BOTH the string AND the buss cable. In effect what this should do is put more "pre-stress" on the limbs at brace, (shorter A-T-A), and consequently provide you with more poundage.
HOWEVER, you must twist the string and the buss cable together to prevent changes in your cam orientation.
Hope that this helps.
