Rich666: First, I can't ski and the bumps prove it. (So I am hoping during the season to resurrect the "Why is mogul skiing so difficult" thread for you guys to answer my questions and make suggestions.)
To All: please criticize my MA below:
What I see about the cute Japanese Girl vs. McGlashan and Ballou is that the Japanese Girl has a pronounced upward extension which causes her skis to release and, thus, she arcs the ski less and carves less far across the fall line.
In contrast, (especially with McGlashan I agree with LiquidFeet) McGlashan and Ballou more often are staying flexed and low longer, thus, keeping the ski on edge longer, and, thus, keeping the ski bent longer and, thus, carving rounder longer across the fall line farther, more often than Japanese Girl.
I also see McGlashan and Ballou use more active lower leg twisting and pushing ski towards the end of each turn to round out and tighten up the carve past the fall line and, I believe, to create a bent ski platform to "lean" on to start earlier new edges while the skis are still far out laterally.
Toward the end of last season I started skiing the bumps in round lines slowly totally flexed. When a recreational buddy who skis differentially but at least as good as me asked what I was doing, I said I was working on "retraction turns." He said "you can't retract if you don't extend." I wasn't extending to him. But I wonder if I was, in fact, extending into the trough, and he just couldn't see it? IDK, but it seems to work for me at my stage of bump skiing "progress." I look forward to experimenting with this stuff and asking you guys and gals about it this Season.
Reading what you guys say about bump skiing and listening to Global Skiing podcast (check out Ballou's, McGlashan's and Beaulieu's and others' hour-long interviews here):
is that in bump skiing you are basically a ball (hopefully not bouncing) falling down the bumps, keeping light contact with the snow to absorb the bumps to control speed like a deadblow hammer loses momentum when it hits an object, so you don't get bounced off the trail, and keeping light ski contact with the snow to continually direct/redirect your path of travel, and keeping light ski contact with the snow to keep your BoS under you so that you are using your skis to maintain snow contact and not your face?
