Man, I've had the complete opposite experience. I had to replace the strings and cables on my pro 38 dually. Only problem was that the specs weren't listed in their guide. Kinsey's called bowtech who couldn't find the specs either. Apparently the pro 38 dually was actually a limited run prototype for the following years black night. Bowtech then went directly to the lead designer of the bow who checked his specs for string and cable length and sent them directly to the dealer. I was extremely pleased and surprised that bowtech went to such measures just to get the string length for me. Sorry to hear you had a bad experience but I tend to agree with the others in that it may have rested more on the shop than bowtech. Who's to say that bowtech wasn't correct in their dry firing claim. I've seen many people dry fire bows in shops by accident and put them right back on the rack. Sometimes the dealer doesn't notice and other times they ignore it and sell the bow anyway figuring that when the next person comes along and buys it they'll let the warranty take care of it.
