I can't remember when they started showing up this season (most of the deliveries might not have been until after your surgery), but I know in the last few cross races in our are there were a LOT of Cruxes, including at least one A-class win. I've heard great things about them, but Kona JTSes are also pretty popular around here. It's not like either of these are bad bikes. I have a Tricross, and while I wouldn't call it flexy (of course, I'm shorter and slower than you), it's definitely not as stiff as my road bike, and I have heard the Crux improves on that, and weight as well.
Personally, knowing the LBS in our region that carries these, I'd favor that, because I'm a big fan of them. And if you want to be economical and reuse parts from your Moto, you could always get a Crux frameset instead.
But I'm sure either solution would work great.
