Hopefully I can shed some light on this as I have owned the 08/09 192 Zealots (the ones with the UPS brown topsheets) and I just picked up my 09/10 182 Zealots from MEC today. My only disclaimer is I haven't got the new skis out to the hill and I won't be able to until Saturday, but I can post a follow-up when I get them out.
I assume you are talking about the 09/10 Zealots with the green topsheet, since this is the first year BD has used a rocker on these skis. The 08/09's were very stiff, and I would even go so far to say that they were a bit too stiff for me and I weigh about 45lbs more than you and I am 2 inches taller.
I dont want to discourage you from getting the Zealots though, they are a fantastic ski if you like to charge. As far as I understand the new Zealots have been softened up a bit to compensate for the planky feel of the 08/09's (they felt like riding an oak door). My other beef about the 192 was that you needed alot of speed to make the ski turn. I felt that dropping down to the 182 with a rocker and a bit more flex would make this ski absolutely perfect (i.e. much easier to turn in the trees and in the bumps).
My favorite thing about this ski is that I can mach down the hill and get going much faster than I am comfortable with, but the ski still pushes me to go faster. The other great thing about this is that it will bust through any crud or crust that you throw at it.
Hope this helps.
