I had some Nordica Park boots with a very very soft flex(80). The boot wasn't suited for my skiing. I'm a big mountain skier, and to make it worse, buckles and parts were falling off to make some serious flex issues.
I ski the One Life too. I didn't notice anything in the case of ski to boot flex issues, just overall boot stabilty, but that is cause of broken boots.
I threw my boots out since they were so fucked. Stiffer boots for me.
Also, I am 6'2", 170lbs.
I wouldn't worry, but if you feel like you might want better support in your overall aggressive big mountain skiing, get a stiffer boot.
