I'm 6ft 5, 200lbs and have last years 183 Blends. They're probably "a little" on the short side, but I still think they absolutely rip!! They measure the same length if not a little shorter than my 181 Pipe Cleaners. The Tip/Tail Rocker is really really small so I don't think you should worry about that. Great ski!
Im 5'9" 160 and I use the 2011 183s as an everyday ski. I have a pure racing background and am pretty aggressive and I almost find them a little to short sometimes. Yet it is still a fun ski: damp, not to soft, can hold its own in anything but blower powder, and an all around good resort ski. I don't ski much park on them since I blew my knee last year but I imagine they would be somewhat on the heavier side. Solid ski and I would recommend it for someone my size or smaller looking for an everyday ski out west. Maybe you could handle it since you live on the east coast.
don't center mount them. i've gotten blends every year since 2005. even with the newer softer model, center mounting is a mistake. these skis ride best at -2cm's from center. i've tried a variety of mounting points and this is definitely the best overall. i use my blends primarily for park but ski them in the pow when i don't feel like lugging my 195 motherships around. i even tour with them and ski legit bc mounted at -2. best spot for sure. again, do not mount center.
