Thank you again for the excellent advice I have received here in the past. Based in part on that, I have done what I now think everyone should know to do when getting serious about skiing: stop trying to save a hundred bucks by shopping online and go to a proper ski shop to get fitted. I am definitely confident I am no on the right path, but I have a remaining concern.
I'm 5'10, 158lbs as of this morning, long-legged and reasonably athletic 41 year old man. Realistically a progressing intermediate, in my head a champion (I do make it in the low silver medal range on the Nastar race course). My main goals are making good clean carved turns and the ability to confidently adapt turning and speed to any terrain. Currently I get down on pretty much everything, looking quite OK on blues, not looking great but making it without a problem on blacks, and screaming like a little girl on double blacks. I had previously skied a pair of Tecnica Inferno Blaze boots, in 110 stiffness. They were not properly sized, so hard to tell if they worked well or not. I did have trouble holding an edge on ice. I have just been fitted at Ski Center in DC (excellent experience) into a pair of Salomon X-Max 100. I added an extra spine screw to stiffen them up a bit, maybe towards 110. I am trying to decide if this is the right flex for me.
I am relatively flexible, without boots I easily get my knees past the toes (by at least 3 in). In the boots, I don't get that far, but I have no problem getting more than one inch over - so I don't completely over-power them, I don't have the cuff hitting the instep buckle etc. There is a fair degree of deformation of the lower boot though. Is this too much flex? I want to have boots that will allow me to grow my skills, but I also don't want to make what I understand is the classic mistake of going too stiff and not learning the proper technique. BTW, it may seem odd to mention learning, but I have only been skiing 4 or 5 seasons, I learned as an adult. I did progress quite fast though, according to the folks I take lessons from and racer and instructor friends.
Any opinion on weather this is the right flexion amount? (yes, all this has been indoor, so I expect a bit more stiffness outside) Should I take them back and shell out another $100 for the 120 flex (which are noticeably stiffer), or would that be going in the wrong direction?
