Replying to Lange Concept vs. Rossi Free X or XX

So what's the concensus out there? Which is a better boot for the park AND backcountry? The rossi free XX or the Lange Concept? Is there any difference as Rossi owns lange? Does anyone know the difference between the Free XX and the Free X. I'm in Australia and ordered the Free XX through the rossi rep here but rossi neva sent my bloody boot over here! I'm seriously contemplating to buy the Concept off of get boards. Lemme know whatyas all think. Arty
