Bought leverlock (basket toe and lever rear bindings) and used std linking bar on my size 45 scarpa phantom 6000 dbl boots. Chose this binding instead of LL fil because I was unsure how it would fit on the narrow toe welt of the 6000. Used for moderate packed snow and up to NEI 4+ ice climbs. Only used for two days but worked very well and was very secure. If you want a pure ice pon look elsewhere. I wanted something that could do it all well. Haven't tried in flex mode but expecting that setup to work well on my heavy hiking boots. Lots of adjustment options for a good fit.
