These strings speak with a really nice, powerful body which I feel have a fairly heavy-ish tension. They start off kinda bright but I think you'll find they eventually settle into a nice, fat, pocket.

I like them because you are not in for a shock in terms of tension or tone if you've been playing upright bass for two weeks and then switch to electric.

I have played a few other flats including Dean Markley, Fender (pretty good), Thomastik Jazz Flats(way too rubbery) and Lakland flats.
