I'm pretty sure the reason for Lizzie being a 172 has little to do with Eric's height, it is more likely because when you have a short ski with a crazy sidecut radius(such as the Eliptical cut), it carves like nobodys business, and because of the 110 waist, still floats well and is great for little back country lines, which is what Eric wanted out of Lizzie.
He is spending alot of time on the Bacon as well though, now that it is finshed with development. And since he is the one who designed both of them, someone could, in all actuality, say that they are both his 'Pro Model'. But why are we arguing over this anyway?
