Well we're back board in hand
First, I want to give a shout out to the Ski Center folks - Jimmy in particular. He took all the time he needed and made us feel like we were the only people in the shop - even though it was packed.
It was kind of funny, we were approached by a youngish looking salesman and we told him what we were looking for (I know my son is a tough fit being so tall with no weight), and he said "um, er, I don't know, let me go get the snowboard buyer" and Jimmy came over and we were off to the races.
He found us three options. While there were others that might have worked, his concern was that once my son starts filling out that he would out grow some of the others.
What we ended up with is a Rome Crail 150 and Burton Mission bindings. My son specifically said he wanted something a wee bit smaller (my words, not his) so even though the 153 comes up to his chin we went with the 150.
We'll see how he likes it when we get to some snow, but I can't say enough about the Ski Center staff. I would go there for everything if they just weren't so dang far away.
