OK, here are a couple points....WC stretches each individual strand @ 900lbs. before assembly. Is this good? Absolutely..NOT! If a WC string is any better at stopping peep rotation, it is because their strings are assembled under a more even tension. My strings(which I make myself) have no peep rotation. Why? Because I apply even tension throughout the process of building the string. With todays string material available, if your string is stretching more than 4-5 twists worth, from initial installation through the life of the string, the string was spun with really uneven tension. A WC string WILL increase bow vibration, alot. There is no elasticity left in the string material. I admittedly have never shot a set of WC strings, but I have friends that shoot them. They all come off the bow in short order. I have examined several sets of them, new, unused. The serving job on every set I looked at...well, if they were a set I made, I would throw them in the trash. I may be a little bit anal retentive when it comes to quality of strings, but if you guys would get someone who really knows how to spin a set of strings make you a set, you would not be unhappy.
