Personally I use 20mm mostly but 15mm would work for a lighter Z-axis. Just remember the Z-axis is handling all the cutting forces so if it vibrates then the tool vibrates with it and you get a shitty finish, excess tool wear and even breakages if bad.! . . . Some areas you don't want to skimp on and Z-axis is #1.
