I'm late to the party! Just saw this set on Deskhero and I'm probably going to pick it up with dark alphas! I like a mono color and clean legends!
One thing I noticed, and its probably addressed in the IC, the numpad is missing some love! With the dark alphas alt kit, a numpad would stand out pretty hard with the light alphas. I guess that only an issue with Full size or 1800 or if you want to match your numpad to your keyboard.
