Between the runs of the Worldcup opening at Solden there was time enough to for me to inspect both the current and last years Course boots in the Salomon Center on the glacier. I had both on, though in the shop only.
The new "honeycomb" Course seems to be softer than the difference in the flex indexes would show (now 120 vs. former 130).
I didn´t find it as much soft as HeluvaSkier describes but it really is a bit too soft for a user of stiff race boots (which is a matter of personal preference etc....)
The honeycomb area is another feature I better ski without
The last year´s Course is, logically, stiffer, and its forward flex seemed to me to make a bigger difference than those official 10 grades of stiffness (we know you can´t take it that literally, it´s sometimes more numbers than reality).
As has also been said, both boots are typical higher-volume Salomons.
The boots that were lengthwise correct size for me were definitely too wide and too high volume even on the first try in the shop
(I have no low volume foot and my Lange LR1 requiered lots of grinding).
Course LAB would be another story but not for everyone.
Dobermann 130 (150 would probably be too much a boot)
or the new Atomic RaceTech (which really is a very similar boot, at least the lower part)
as well as Head or Lange could be good possibilities.
Last but not least, "to order them, hoping I made the right choice" - I hope you try them first!!!
