Not bad sticks, I don't use 7a's anymore, but I remember being pretty happy when I got them. I mean, They look awesome, there's no denying that, and they play pretty well. The only problem is, the black finish gets eroded slowly as you play, especially when it comes to the high hat. I guess if you play jazz, these sticks will pretty much stay a solid black.
Anyways, good sticks, and a good idea behind them, but you can get better quality sticks for a similar price, so keep that in mind.
