I'd like to start off by saying Pro-Mark is my favorite brand of sticks and the 2B model is perfect for me. They have the most pure, organic, comfortable feel of any stick I've used - and I've tried a lot. I was recently blessed with a brick in the 2B model and was very excited, though my excitement soon died out. I did the "roll-the-stick-across-a-table" test to check each sticks balance and, sure enough, 4 sticks (both sticks in two pairs) were wobbly. This has happened to me once before. I'm not sure what's going on with Pro Mark, but 4 sticks being unbalanced is pathetic. I'll continue using the other sticks in the brick because I'm faithful, but they need to fix the problem - it looks really bad.
