Does anybody use two Sets of limb savers? Is It worth the Money?

I have tried it and found that there is not any appreciable gain by going with 2 sets.

I have two sets of vibrashox on my ultratec. No vibration and whisper quiet. I know it's probably over kill, but I had a second set given to me.

When I use only one set, I can definately tell the difference.

Would using two sets of limbsavers have any impact on speed?

I have a pair of the originals and a pair of the ultras on my takedown recurve , they made enough difference to justify the cost IMO . The difference in the noise and vibration is noticeable .

I just picked up another set I'm gonna put them on and see what happens. if they don't do anything I'll have a extra set!!!
