I just had the shakey hunter put on my 04xtec, replacing the wisker biscuit. I had the guy at the proshop pu it on and do the tuning. when we paper tuned it their was a big difference between the two rests. the WB wouldnt tune quiet as nice because it ran out of adjustment to the horizontal side. I tried another shop to get it tuned too and same result. I must say I really liked the idea of the wb but within 10 shots I could tell I had better accuracy withe th TT. Just my 2 cents!
