+1 on the Weichs. I've had the same set on my bass for two years now, I love it. You've got to play them in for a few weeks, but it's worth it, and If you want more tension (resistance) just raise the action a bit. NOW...if you want to bow them I really recommend using a fresh cake of pops rosin maybe from here
http://www.bassrosin.com/ and re-hair your bow with black hair, this combination gives you more grab with weichs.
My luthier recommended this to me and it helped a lot. I love weichs pizz or bow.
Good luck.
