Cute dig at the end there, but I will answer your question regardless:

I would want calipers honestly. My fear in that situation is that the stopping power does not offer the modulation I would want. If you are in a situation like that locking a front wheel will cause a crash much faster than having too much speed. When the roads are wet any brake you have will be able to lock your wheel. The trick is toeing the line on locking your brake. You are probably mis-interpreting the feel of your brakes and feel that they lack power when infact they are just modulating it.

For example on the new SRAM Red calipers (The ones that use Single-pivot style design) have a good bit of initial bite and then through a long part of the throw it feels firm and the power is "good" in that it doesn't cause an instant stop you just get to modulate your power. If you really start to squeeze though the power really ramps up near the end of the throw. I suggest that you take the recommendations we have here and experiment with braking technique.
