Pod HD Pro Rack & Pod HD500

Hey people, first post here. im a long time user with my line6 m13 through digitech whammy,spacestation, dunlop crybaby, boss noisegate. im tired of hauling all this gear, so im looking into the line6 hd500 im sure i can acheive all the crazy sounds i do with my m13 and then some. BUT! im considering purchasing the Pod Hd Pro rack as well to keep in my studio. so when i create patches for a song would i be able to transfer the patches to the line6 hd500 when i hit the stage? most people would probly think this is silly to buy both but i would hate to constanly disasemble the pro from my studio rack to play a show. or constantly hook up hd500 to my studio rig to record.i just love convinience. and i cant decide if i should sell my line6M13 too.does the hd500 have an easy looper to use live like the M13? i would like everyones opinion & answers, thanks people.
