Need some advise on boot placement- just ordered a new Radar 2017 67" Senate Graphite. I have been skiing on a 2013 Senate, not what was the C, it is the softer one which I guess would be equivalent to the Alloy construction now. They only had two builds back then. And I ordered one of the 2016 Profile bindings for the front. I have several sizes of the Vector boots and have always felt they were a little soft on the support side. I use a rear toe plate but I am going to try their HRT half-boot in the back. My buddy had one on his Radar and did not like it. My question is boot placement. What is the best way to measure the placement of my current boot to setup my new ski with the same position? The Radar site recommends starting at 30.5". Looks like that is taken from the tip to some point on the front boot. For what it is worth I am skiing a slalom course in public water at 15 and 22 off at 31.4mph. Thought it was time to try a better ski and boot for comparison.
