They are all the same mate, just use the 2014 versions and I suggest you go 13" rather than stock 12.5 inch for a smoother ride and better handling. The 13" have longer travel and therefore softer springs for the same carrying capability even in HD version. If you weigh over 250lbs and whether or not you even occasionaly carry a passenger go the heavy duty (HD)version. They should be fine solo at least preload setting but give you extra capability with a pillion and luggage load.
Black is cheaper than chrome too.
