The medium brush works really well in the gym so it's the one I've used the most, wish I could buy that one on it's own now.
I agree that the big one comes in handy on boulders that haven't been touched in a while, medium one is good outdoors too and the small ones do the job on tiny holds.
the big brush on its own is brobably worth the money, its really amazing. with this you can get rid of moss and dirt easily
