I use Grindstix 3A's
Grindstix, I believe, runs sickdrummer.com (or vice versa)
These sticks are the best sticks I have ever used. The are well balanced, very durable, almost no shock and havn't broken in 3 months. (im still on my first pair)
Alot of hard hitting and grind drummers use and endorse them (Erik Park, Adam Jarvis, John Longstreth, Marco Pitruzzella, Duane Timlin just to name a few)
They run about 12 a pair and get mailed to you in about 4-5 buisness days...
I must say my speed and control have increased more using these sticks, than the usual
Vic Firths I used to use years back...
If you looking for a hard hitting drum stick with great durability and many options.... You should check them out...
