you've already picked the Lange RS because you already own pr, or have demo'd it?
my guess is that a good percentage of existing Fischer boot dealers will prolly put in the Vac system and boots.
being in Upstate NY (above Albany) I'd think there's likely a dealer reasonably close. Maybe get into a pair of this year's demo and eval the performance side of fischer boots.
I'm pretty picky on boot performance and found them to be as good as any boot I've had some hill time with.
and if you have some foot/fit issues, the vacum might deserve some consideration.
if you're a young guy and have lots of hill time every season and get new boots every season or 2, then it may not be that big a deal to get something now, and consider again in the future.
if you like to hang onto boots for longer, 3 or more seasons, then it may be worth waiting...
I have longer, relatively thin lower leg, so how well the boot upper wraps properly is real important to me. Fischers wrap my leg very well, without overbuckling. They follow the leg forward flex well and don't 'gap' . They give a very progressive resistance without shin bang.
When I went looking for boots last yr, I immediately went right to Lange. I was blown away that I couldn;t find a Lange, in my flex range, which could accommodate my high instep without sizing up, like the many older Langes I used to ski...
Obviously still a good performance boot, but just not for me.
If the Fischer Vac system does work even close to what the claims are, it should change and add to what our expectations are of how a ski boot should fit.
not likely that it will be the answer for all skiers, and may not work for some
but I think it's worth a look-see
for the past few seasons I've held that Kostelic is the best technical skier on the WC ( for SL & GS, and now holds his own in the big speed events) and his Fischers don;t seem to hold him back...
Yes he's getting paid, but soooo many other racers from so many other national teams are on Fischers. They can;t be payin ALL these racers. Once in the team pool a manu often still has to prove that their stuff will give a competitor the best performance edge.
Fischer knows and is about ski racing. I think they've done their homework well.
