I haven't used them in a while but I put them on my BTB 400 and Im in love again. They are nice and tight for a roundwound. They have lots of percussion and thud too. They feel good and they sound good. I can use the 45-100's with these because they are stiffer. The 45-105's feel like cables however. I've been using DR's and although I like the way they sound they are a little looser than I prefer. boomers are back baby!
