After 2 seasons on my Lupo AX 120's I have decided that they are too soft. I currently run an ID Pro liner from some krypton pro's that my local ski shop had. My previous boots were Il Moros, which had a ridge on the inside back of the upper cuff, where you could slide these pieces of plastic that would restrict how much the boot could flex. My current boots lost that capability for the walk mode I presume.
I feel more in control in these boots than I have ever felt in any other pair and have had a significant amount of shell work, so I would prefer to avoid starting from scratch with a boot that has 5 more arbitrary stiffness points, or even more shell work to a narrower shell to get an extra 10.
I often find myself over flexing the boot in hard turns with my ankle nearly reaching its max foreword flex. I've also been told that I have the stiffest tongues Dalbello makes (They came with p tongues, but switching to B tongues didn't help much and did not have the quick tongue removal switch, requiring me to pull parts from my Il Moros)
