I just ordered a set of these Heritage strings. I am excited to try them. They have gotten mostly really good reviews. Kolstein's description of them sounds very interesting. He says they approximate the great feel of gut, but have more of the tonal characteristics of modern steel strings. This sounds to me like what a lot of us are looking for. The Eurosonics that I have been using do feel nice and have sounded really good in some situations as far as pizzicato goes. I think that I have kept using them mostly because of their exceptionally nice feel. I have had enough of not being able to bow these - I feel like an incomplete bass player unless I can bow the strings. So, I am hoping that these Heritage strings will come through for me. If I don't end up liking these, I think I might just go back to where I started and deal with Spirocores. Any new comments on the Heritage strings?
