But the trade off is more than worth it for me.
If I went to a much stiffer boot my mogul form would suffer and I wouldn't be able to ski as many hours during the day.
Super stiff boots are way over rated. I can still carve rails with my 90 flex. If I can find a boot that fits me as well in a 90-100 adjustable flex it'd be perfect for me.
Why go to a 130?
I had a similar revelation this season.
I'm 5'9, 165 lbs. I've been skiing Lange 120 flex boots for years.
This year I got a Falcon CS Pro which is rated at 110 -yes, I know flex ratings across boot lines don't correlate. still, it's a point of reference.
On my bootfitters suggestion I removed the two bolts on the back of the boot which allegedly diminishes the flex from 110 to 90. The difference is not great, but I prefer the 90 flex. The boot is more forgiving in bumps and powder and the only time I miss the stiffer boot is ripping off high energy turns on groomed terrain which isn't my typical terrain.
My thought is that a super stiff boot isn't needed by most people on "shaped skis" because we no longer need to drive the ski as much from the tip and instead roll from the ankles, knees & hips.
