As someone who got his start in drumming with marching sticks, these things definitely induce a bit of nostalgia for me. I love the weight of them and the balance is wonderful.
I currently play with the AJ2's for most of my shows, but whenever I feel like my muscles are fatigued and I'm going to need more control for the set, I pick these guys up. The diameter allows for a really solid grip, and if you're a heavy-hitter, you can really wail away with these sticks. My rimshots have never sounded thicker than with these.
All of that being said, these are the "American Jazz" series, and the amount of dynamic control that you can achieve because of the size and weight is incredible.
Great sticks, fair price, and noticeable Vic Firth quality. No obvious cons to mention.
