I'm a beginner: playing drums less than 3 years. 
Tried before: Promark, VicFirth, Agner. 
First of all: the sticks feel lighter and thinner compared with 5A's of above brands. 
Second of all: the wood seems much harder, very dense. I can feel the vibrations returning, especially from the ride (this could be due to my poor drum technique). 
Positive is: the sticks last longer compared with the above brands. 
Also the tip is much bigger: I like this a lot. 
The balance seems great. 
Negative: although the wood is very dense, it seems the sticks are a bit light for a 5A. I'm playing Rock (coverbands) and the sticks seem a bit light for some of the heavier stuff we're playing. 
Despite this: the best stick I've bought so far.
