I'm using one right now and have been for several months now. Chad sent me one to field test about eight months ago. I like it pretty well. I've found that it still has enough elasticity to be safe on about any glass laminated bow (probably self bows as well but I don't shoot them so can't say for sure). I'm shooting a fourteen strand flemish on a '69 Bear T/D with Stahl limbs, 72# @ my draw length and have found stretch to be noticeably less than either B-50 or B-500- B-50 being the stretchiest of the three with a slightly lower tensile strength per strand. In fact, when Chad made the strings for testing, he said he wanted the results after thousands of shots- I guess I oughta get back to him by now. GY
