Caliper and canti-lever brakes properly adjusted should stop you. They have plenty of power for you to do an endo, fly over the handle. Down side is the effect of wet brake pad, wet rim, grim on the rim.
I'm not too terribly concerned with added weight of disc. full water bottles, (I've known to carry four 16+oz bottles in really hot weather), extra layers on extremely cold weather will add far more weight than the added weight of disc. Only place where the weight is of real concern is if your race is a mountain stage with finish at the pass. Most races are crits so I wouldn't worry about it.
Crashes on a bike even in a pile up, I have never gotten my body parts in someone's wheels. Come to think of it, I don't think I've been in a midst of a pile-up.
To me, choice of disc, cantilever, caliper is like choice of bike color or brand of bike frame and components. What really matters is physical and mental comfort.
