@muzza1973 - you sound like my tennis twin except I'm only 5'10! I'm in exactly the same situation coming from a Radical Pro (go muzza!) via a Prestige MP. I demoed the Aeropro out of curiosity and loved it with the stock string (excel at mid tension). I tried a friend's previous aeropro and felt it on my elbow after just 10 minutes but spent an hour with the 2013 and my arm felt fine.
I'm carrying on with the Prestige MP but the Aeropro is an itch I'm just going to have to scratch.
