After eight months it seems my Obligatos might be going a little dead on me. They are not bad by any stretch but I'm starting to get the itch to try something new. From all the posts that I have read about the Superflixibles they seem like they might have the sound I am looking for. I actually love the Obligatos but I can't resist trying something new. I am tyring to start bowing more as well as playing pizz so I a very interested in hearing from folks that have had both strings. Peace . . . P.S. My bass is a hybrid Christopher just under a year old.
