I bought these sticks for two main reasons:
1) Keith Moon is my favourite drummer ever.
2) I use 5A most of the times.
These are basically 5As, slightly shorter, thinner and lighter. I mean very slightly, almost imperceptibly. They feel nice, delivering power and speed, they have a good tip which sounds really nice on my cymbals, and they have a wonderful Union Jack printed on. I was looking for something a little lighter/shorter than a 5A, I didn't want to buy anything like 7A and stuff like that, and then I discovered that my favourite drummer's sticks were exactly what I was searching. Sign of destiny, for sure.
