This would be wrong, and just repeating old wives tales.
The Marker Jester has a plate on the rear on their standard version and only adds one on the front for the demo. This one plastic piece doesn't affect weight in any appreciable way, and I'd be extremely surprised if it had any REAL effect on flex.
Alternatively, demo's allow you to change mounting position at will to see what works best, change boot sole length for friends and family use, makes them much easier to transport if that's an issue (I can bring 4 pairs of skis and one set of bindings), and make them easier to sell later.
All mine have demo's, and I've also skied the fixed ones, and there is NO difference.
