I'm older than you are, but I also hit a one-handed backhand. Whenever I try a frame that's on the lighter side than I'm used to, my backhand and volleys are the first shots that lose their mojo. I enjoyed the old 6.1 Classics some years ago when I was more of a serve & volleyer, but I've found more control around the baseline with a softer alternative - evolving into more of an all-courter.
The Volkl C10 has been great for me, but the Organix 10 could be a smart one to check out, too (haven't tried it). I run my C10s with snug synthetic gut and they give me zero discomfort, even if I'm keeping a very busy schedule on the courts. They're a little peculiar, just because they have some flex in their hoops. Although they're a little bit "tip dead" this hasn't been a problem for me at all. As soon as I switched into this racquet, my strokes really came alive, but I've still enjoyed enough of that 6.1 sort of performance with these that I haven't missed those Wilsons at all since my switch.
