fritschi freeride/marker duke drill patterns

I did a search.

Was wondering how different or the same the drill patterns are on the two bindings. I'd like to not go too far off boot center if I decide to get some duke shorts. Would there be much of a problem switching from one to the other bindings?

I noticed tons of play in my fritschis up at Meadows a couple weeks ago. All this talk about how burly the dukes are is making me salivate.

was playing with a duke jig and a freeride jig the other day and it seemed to me there would no problems at all mounting over a ski drilled for freerides.

that's what I needed to know. Thanks.
