Unfortunately, you won’t find many people who have experience with both the smooth track and the graphene track.

I have the graphene track and have done some crazy descending in absolute downpours. If you search the thread you’ll see my impressions. But basically, with Black Prince pads, it’s workable in the wet, which is more than can be said about some other brake tracks. My buddy has Farsports with a super slick brake track. He can ride uphill with the brakes on in the wet. He also descends like a demon - out of necessity.

The main downside with the grooves is that is SHREDS the pads if you press hard and in the wet, it feels a lot like nothing-nothing-GRAB, which can be scary if you don’t have a lot of grip to work with. Kiss any semblance of fine modulation goodbye.
