as mentioned, gloves are too much trouble for a 15 min ride. you have a jacket with wiring inplace?
get some goretex gloves for <$100.
grips are nice if you ride through a big drop in temps. for instance it is 60F here but ride up the mountains and it drops 20 deg. I see them as a good way to keep from freezing on short stints
