Grip on slicks compared to threaded tyres

riding slicks in the dry is obviously never a concern because I'm not thinking of sliding. The comfort allows me to take more risks racing. so grip is the same in my mind in the dry, whichever tire choice is made.

However there's a lot of evidence to suggest racing in the wet shouldn't be too much different in the dry. There is no aquaplaning because the surface area is so small. There should be no reason to slip and slide more than using a threaded tyre in the wet if using equal tyre pressure - the grooves do little to provide added grip according to some specialists.

Does anyone have anything to add to this other than what Sheldon Browne or anyone else says. I think it's more a mental thing to go quick or not in the wet on slicks compared to threaded tyres, a battle I'm struggling with.

going downhill in the wet on slicks, turning left and right and braking at speed should be no more risky than threaded tyres? Discuss ?
