Hey guys. I've been using the KPS88 for a couple of years now, and out of sheer restlessness, I've been looking to try something different but not too different. The PK Ki5 PSE has the same static and swingweights but has a 100 inch headsize vs the 88 for the KPS, and is just two points less stiff than the KPS. This, to me, falls under the "different but not too different" category for me. I was wondering if anyone here has used both frames and could compare the two (spin, control, serving, etc.) Thanks!
