Well more like beginner/intermediate. I catergorize my level on experience and since I don't have as much experience other people, I call myself a beginner/intermediate.
Nah men, go ahead those bindings kick ass. Never buy something at your level, always something better that you can grow into. I wish I had my 390's since the beginning, they light and very responsive.
I've ridden targas for a while and they are pretty awesome, they were my first advanced binding. My only complaint about them was that when I would barrow my buddies Ride Beta Movements I would always find that Ride had some more dampening in their bindings, which is why I'm going to go for the CAD bindings next year. But I really don't have any complaints about my Targas, I'm just the kinda guy that likes to upgrade unnecessarily. Another plus about the Targa is that it is very customizeable too.
Targa`s are the kind of binding that will benefit any rider from a never ever to an advanced rider. When you get them, you may find that they feel far more responsive than the bindings you may have been using and you may think they are a bit touchy. You will very quickly learn the feel for them. I highly recomend any Rome binding.
