I bought these sticks as I was looking for some thin, light sticks to use for playing at a lower volume in a small church room. The quality is great as you would expect from Vic Firth and they feel really nice in the hand. The response on both skins and cymbals is great and, unlike heaver sticks, you can really tease the lighter tones out of both without having to hold back too much.
I wouldn't recommend these for heavier playing as I doubt they'd hold up for too long but that's not what they're designed for. I don't use these for Jazz playing predominantly myself but they suit the more gentle style of playing that I need to use in an enclosed space.
Great stick, great price.
