Wow, Did you ever try the Fender 7150M Pure Nickel Roundwounds? I would have probably never thought of buying them myself, but since I got them as a present I put them on yesterday. And I was really surprised! They sound awsome. They have a vey punchy attack, a nice growl, yet they also sound very "clear". And when slapped they sound crisp and still punchy, just how I like it. But keep mind that I have just put them on. I got no idea how they'll sound in a couple of weeks. Also, I have not too much experience with strings. Up to now I have only played the D'Addrio (sp?) XLs and the Ernie Ball Hybrid Slinkys as well as the factory strings of my Yamaha.
