Stay away from tele and alpine treckkers! I have used dynafit for almost 15 years and they work great! the marker touring bindings and fritchi both work great aswell. dont worry about the support you think you need from an alpine boot get a light touring setup and you will be happy for a long time. I personally ride the dynafit din to 12 binding, dynafit titan boot and a 188 k2 sidestash! For me its the best setup to have this year. I have been a ski tuner in jh for 19 years and have worked with all the touring bindings the ones I mentioned are the most reliable. treckkers are the cheapest way to go if you have no money but the worst way to go. IMO wayne!
