Do you think the ski's listed above are wider than I should be looking at? The Tigershark's are 168 and short for me.
I think the Blizzard Thunderbird R15 WB is about as far as you would want to go for Ontario and western Quebec. The tip rocker will help make things easier in the non-smooth-groomed and not-ice conditions.
On the other hand, if you decide to build a quiver, you should go wider than what you are looking at for your storm-day/travel-to-deep-snow ski, and while you're at it, pick up a pair of skinny long radius full-cambered skis too (for bigger hills and higher speed turns).
Regarding moguls, I don't see what all the rush is to get wider skis for moguls. Skinny skis work just fine in moguls, but tune makes a difference (I left my old Volkl P50 F1 Energy skis at 1:2 just for moguls), as well as softer flex (so you don't bridge the smaller ones), although maybe that (stiff flex) is more of a problem in Moguls for lightweights like me.
