Never used these before, but now use them all the time.
A great feel and sound,around the kit, feel good when playing and give more freedom of movement because the grip feels firmer and you don't feel like you're going to lose your sticks during a more 'frenetic' piece of playing,far better than my 5A's.
It's hard to explain, but I feel more able and more confident when playing 'difficult' patterns using these dowel sticks and the sound is somehow 'richer'.
I can say, in all honesty, that my playing has improved using these and I've been playing for ten years.I'm amazed and I'd say purchase a pair and give them a go but sit back a bit as they have a life of their own!!
