I've transitioned from my old 6.1 Classics to the Volkl C10 Pro, too. It took me a while to really settle in with these frames, but as soon as I started playing them, I was more comfortable and consistent from the baseline. With a bit more flex, I get more spin when I want it, but this Volkl is nice and stable so I can crunch my serves or pop decent volleys just about the same as I can with my old Wilsons.
The Donnay is a wonderful "old school" frame with even more flex and exceptional feel. There's a little less pop for me in this racquet, which can be noticeable when I want to serve hard, volley with real authority, or hit a solid block return of serve. Superior control with the Donnay makes it a lot of fun, but I can hit harder or softer with my C10's and they're also really comfortable for me.
The mids from Volkl and Boris Becker might be interesting along with the newer Rebel and Ignite (looks a lot stiffer than the Rebel) in Prince's EXO3 line. I like to read the feedback on frames to see what other racquets the players compare them against. It can be helpful when you find a frame that replaced the k 95 (in your case) for a few hitters, especially when they discuss the differences.
