I made up an 8 strand D97 for my Mahaska, which is not made for fast flight. It made the bow a joy to shoot. The hand shock with B50 gave my elbows fits. With the skinny D97, there is absolutely ZERO hand shock. I wish I'd gone with a 6 strand because my serving is a bit tight with 8. I'll probably do that eventually. I padded the loops to 16 strands, then added yard (see the before and after pics).
My thought is there is no way the tips are going to wear any worse with my setup than with B50. I also can't see how the lack of stretch (which O.L. disputes by the way) can hurt the bow. Since there is less hand shock, the energy is obviously going to the arrow instead of the bow, so I see no need to worry about the limbs.
Here is the bare B50 string:
And here is the same bow with the yarn wrapped D97:
I know this is not a Bear, but the principle should be the same. I may whip up a six strand for my old Black Bear, yarn the loops and see what difference it makes. The skinny D97 strings are supposed to be quieter. My bows are pretty quiet to start with, so I'm not sure about that. The reduced hand shock makes it well worth the investment for me.
