it wasnt a problem on Vtecs as far as I know
Some of Hoyts "short" 05 bows were having serving problems, especially those that went to an aftermarket cable slide. The factory Hoyt slide was recommended, because it didn't torque the fiber as much. I believe there also was an issue on some cams that had sharp edges that were cutting servings, especially when a thinner cable slide was used. That would cause the serving to catch those sharp edges. Some shooters were reporting broken servings, even with Winners Choice type fiber, in less than a couple of hundred shots.
The photo I enclosed of the spread Trykon serving, said that was less than 100 shots.
looks like ordinary string stretching to me which occurs on all bows that are shot on a regular basis
That's true to a point. Shooters today are spending more than ever and expecting more also.
Most "full time" archers/hunters in the last few years have laid out an average $650 + or - for their stick. Upon having fiber problems, laying out another $75 to $100 for "quality" fiber.
Both Hoyt and Mathews "swore" better fiber on their bows this year. I haven't heard yet from any 06 Mathews guys yet, but time will disclose that. The Trykon reports have been discussed on Archery Talk already.
When a top line/price bow is purchased and one must spend additional sums of cash to "get it right", there's something wrong with that company's quality control.
Both H and M are great at making good for product problems, but these are not new issues. They have to stop "counting jellybeans" and causing their customs, time and inconveinance's.
