I'm currently skiing with Lange WS130, non-race version boots which are approx. 5yrs old. I ski mostly on blacks and double blacks in the East. Ski mostly in trees, crud, powder, bumps in all sorts of conditions. No racing. I'm looking at the latest Lange boots for 2012 and see they have revised the RX 130's. I take it that this boot has replaced the older Banshees. Wondering how this boot stacks up against my older WC 130's? Concerned about the more stand up stance (less forward lean) and the quality of the liner.
