yeah, madtrix are a pretty solid ski for sure.  maybe a fatter ski would be more forgiving.  Pistols are pretty light considering their size and are really versatile skis, but i think most companies make good fat twins.  you could probably go a little shorter than the 190s for example but with a shorter wider ski you would still have same surface area (and all the benefits) but it would be easier to handle.
food for thought
