Thanks for the confirmation. I have the 1/4". I wonder if the larger size in combination with the stress that is put on the aluminum is causing it. Another part of it may be that even though the parallel limbs help reduce vibration and stress in the horizontal directionon the bow I would think that the vertical pressure is increased dramatically and that would try to squeeze the seperated strings together. I'm definitely getting in touch with them M5. I've only had it on about a month and shot6 or7 times.

Besides the color I liked how slim the peep was.
