I first tried one of those when I caught one at a Mastodon show, used by Bill Kelliher. I thought it'll be a fun thing to try for a second, with such a sharp point. It took me an hour to decide that I don't wan't to play with anything else.
I immediately gained speed, consistency and control just by switching over to those. I thought those pointy ends will lead to less detail but it's the opposite, I can control every move way better. Used to play Tortex Wedge 1mm, haven't touched one since :).
