the best fit for fast and heavy players. I found out that this might not be the best fit for me personaly, as i'm aiming for more "feely" yet heavy and progressive kind of playing, but it sure does the job... Once you get the hang of it, you can blast and groove with great power and terrific rebound response.
For comparison with vic firth rock, these have softer yet heavy rebound, are slightly more thick so you will have to count more weight with these tree trunks.
