Thats busted. I feel like you have so much extra weight with frame bindings and your heightening your center of gravidity which i never really have been a fan of. I gues if your just going up there for a couple turns sure but I dont really get that.
It really depends what you trying to do.
If youre buying this boot with pins but without walk mode: I dont think you are doing extended trips. probably just slack or resort access stuff.
I dont think the benefits of a more natural pivot point and weight (efficiency) for a kinping or cast system would outweigh the losses for range of motion. you might lessen the (effort per step) but you will undoubtedly add 20% to 50% more steps because each stride is shorter. I think the overall workload would be pretty similar and would all just come down to preference.
Lets say hypothetically:
- 1500' climb (ignoring horizontal distance because range of motion and glide efficiency would matter more on flat)
- 10lbs for pins no walk mode with cast, and 15lbs for frames with walk mode (1/3 more weight)
- 2' per step on pins no walkmode, 3' per step on frame w/ walk mode (1/3 more range)
- 90% efficiency pins, 80% efficiency on frame w/ walk mode
If difference in workload = (1+(1 - efficiency% / 100) ((climb / ft per step)(weight / 2)
pins without walk mode = 4125 step lbs
frame with walk mode = 4500 step lbs
ok nvm. i was wrong.
pins without walk mode are superior to frame with walk mode with these assumptions. assuming the difference in range of motion and weight is the same then they cancel out and efficiency is the only factor for effort. at the same time my assumptions are probably flawed, and i dont think step lbs is a great metric for effort. id prefer the extra stride on flats and probably the smaller weight per step on steeps.
people just getting into alpine touring now have it really nice. Before if we wanted to take a nice ski up a hill we had to use trekkers or MFD all time plates. often without a walk mode. I guess i would just revert back to what i know instead of giving something new a chance.
