I think that video, while informative, fails to really consider the difference in real estate sticks with that angle on the step have. LWCG and Tethrd both have that angle because the standoffs are short.
A LW/Novix/Trophyline stick is 4" from the table to the middle of the step and to the tips. A Tethrd stick is 3" from the table to the middle of the step and 4" to the tips. You can either look at it as "it's just an inch" or "It's 25% less space." Same with weight. You can either say a LW/TL/Nvx stick is "only half a pound more" or "It's 50% heavier."
The high speed, low drag, uberlight sticks definitely get there by shaving material and real estate. Pros and cons.
As far as what "man feet" are, Google says here in Yoosa it's 10.5. For once in his life, Nutterbuster is above average!
