I've been using Insanos for the past three seasons. Keep in mind I am a backcountry rider. So I can't really speak to dampening and how great they are for park.
Insano's are one of the lightest boots out there. They still keep your feet warm, mostly because they use Intuition liners. The boot holds up fairly well too, though I am finding boots these days are just not built as bomber as they were "back in the day". The tread is nothing special. Not Vibram, and certainly could be more ideal for us backcountry guys. Overall it's a solid boot.
Flow has a couple of new boots coming out that are interesting. Very light, maybe lighter than the Insano. Vibram tread, dual BOA. The Talon is one of the models. Not sure on how stiff they are going to be. The model I played with at SIA appeared to be fairly stiff though. Quality wise is another question, though they did look reasonably built.
Thanks for the feedback. The dampening I'm looking for is just moguls/chops and natural drops/jumps. I doubt I will be doing huge park stuff anytime soon. I will probably do a little of snowshoe/boarding this year as well. I hear you can use a normal lace on this boot if the BOA breaks.
I will check into the Flows, but it's always a crap shoot with fit. The only other boot I was interested in was the NB/686 as the NB shoes fit me well. But they are already sold out in my size
