Thanks for the suggestions guys, i have looked at all those other types too, but narrowed it down between the Compressors and Alembic. They are both Compression wound strings, so slightly smoother then rounds, but still sound like rounds. Compressors dont seem to be that popular, but there's some great reviews of the them over on talkbass. They are also cheaper than the Alembics, so figure i'll start with them first and see if i like em. Thanks!
