My expierence with them is that they have huge backend reactions coming off the overlay on onto the wood (oak) backends IF they been properly prepared.
If not, a lot of carrydown does occur.
My best set have come with a low load particle ball so that you dont get a big jump when it hits the backend, also good for any carrydown that occurs. I would generally switch to particle pearl..
