Those Sadowskys sound like they're worth a try.
However, I find Rotosounds to be quite useful! Been using them for several years now -- last really long, play really smooth, sound really loud...on my Yamaha TRB 5.
The B string could use a little more depth and definition...it's always the first one to die -- after about 3 months of steady gigs.
I do have to say I got 100 gigs out of a set in 2006 before the G broke -- this was on a loud blues/rock gig -- and we played & played.
The Rotos get my vote.
