No experience, so feel free to disregard my speculations. Trying to reason it out, though:

(1) My Pearl AmFibs are too warm for me over 25F -- they'll get saturated in sweat (and lose insulating properties shortly thereafter).

(2) I can adjust my jacket sleeve cuffs to cover the tops of gloves, so rain won't run down into the glove.

(3) Neoprene gloves, again IME, aren't sufficiently warm below 40F, but are waterproof.

So, putting these together, I'd suggest a layered system. Choose gloves that work around 45F. Get neoprene gloves about two sizes too big to go over the inner layer glove. Then take an extra pair of the inner gloves, so you can switch them out after 2-3 hours. Make sure your jacket sleeves go OVER the tops of the neoprene gloves.
