I would pay attention to any strange noise I heard from a supercurve. If I heard a strange noise, I would start checking the brace height and tiller each time I took the bow out to shoot it, and if I noticed any unexplained change in those, I would stop shooting the bow until it was inspected.
After shooting bows almost every day for more than 30 years, I have had only two bows blow up on me: one was an old dual shelf recurve that someone had given me, and the other was a less than 6 month old supercurve. I have a good friend with as much experience shooting bows as I have, and he has had only two bows blow up on him: both nearly new supercurves. I was shooting with another friend this morning, and his nearly new supercurve blew up on him, which is the only time he has had a bow blow up on him, I think.
I don't know why this is happening, but I have to believe their are higher internal stresses in a supercurve than regular bows, and the safety margins are thinner than usual to cut down on the weight of the limbs and get the enhanced performance they are looking for.
