One point to remember, if you're going to use one pair of skis for both lift served skiing and touring then Fritschi are probably the way to go (easier to pop on and off for lifts).
All the Dynafit users I know (including me) started off with Fritschi. I don't know anyone who has switched from Dynafit to Fritschi, however there are a lot of people who start with Fritschi and stay with them.
The big decision to make with touring skis is weight. Essentially the heavier the ski the better it skis, but the harder it is uphill. It's always a compromise and you'll never get it right.
You have to decide what sort of touring you're doing (multi-day hut touring or a bit of slack-country) and choose the weight of ski based on that.
