I know a lot of people say you can't tell much of a difference, but they are great, so if you are thinking of upgrading, do it. I just even upgraded from a PureSound 20-strand to a PS 30-strand and it made a world of difference. The 30s make the snare so wet and responsive - it was like I sprinkled a little bit of instant sex on my drum. Really increased my dynamic range. Gave it a bit more ring, which I'm gonna' cancel out by going to double-ply heads (which I need anyway with my round-headed sticks and heavy hands) PSs are well worth your extra few bucks.
