good feedback, thank you. I spoke to a longtime mathews pro, ran the shop for many years before retiring. He now works part time at a shop that does not sell mathews. I asked him which he liked best and he said the switchback and the z7 are in his opinion, two of the best bows they've ever made. Somewhat consistent w/ what I've seen here.
I may call the local shop and see if they have any leftover z7's.
