I took the plunge and bought HZStrings the other day. I think the soft, lush sound it offers is quite remarkable. Lots of chatter about how disappointed certain people were with it not being bombastic enough. I find it remarkably versatile. It also layers extremely well with SF Chamber Strings as people in this string referenced . If anyone is on the fence about purchasing, here's a little snippet of something I'm working on where I layer the two. It's just my acoustic guitar and HZS and Chamber Strings (and a little Harp Swarm).
Agree about it being remarkably versatile. Enjoyed the guitar work!
