The Team is very similar design to the 09 Murray but made even better. I have not tried the Audios yet but have a pair in the mail. I have heard great stuff about them though. Murray will have a boot but I don't think it will be out till mid-late season still.
If you like stiff, then I would go with the team or the Marek. Both boots are going to be lighter than your current setup otherwise look at the Ronix Cells or CWB bindings as they are even lighter.
I looked at the Marek but on this site they got really baddd reviews. I can't afford new boots every year, they need to last. This takes me back to TEAM or Audio? Thanks
