Based on recommendations I found here, I tried out DR Nickel Lo-Riders on my bass today, and all I can say is *WOOT!*
It's the perfect combination of feel and sound. They're not as slick as the Elixir Nanoweb's of course, but they deliver that nice Fender "growl" I've been looking for without chewing up my fingers.
Thanks to all who turned me on to these!
