Great drumsticks overall, they're durability is good and the sound is even better, i played them on an acoustic kit that as some really old cymbals, and it made them sound pretty good, i was impressed by the sound that the sticks could take from the cymbals.
I also played them on my electronic kit, and it feels as good as it is with an acoustic kit.
They really are balanced, if you try to spin them you will have no difficulty because they really are that balanced.
Overall they are one of the best pairs of sticks that you can get, you're getting what you paid for, they sound great, they feel great, the finishing is great, if you have the oppurtunity to buy one of these, go for it, they're worth it, you won't regret it.
