The line of compression. I thought the LOC was vital throught impact only. In that case, as long as the SS-plane is aimed at the impact point from release to follow though (between 3-4th parallels) proper LOC should follow, no matter the SS-planes orientation before reaching 3rd parallel. Keeping planeshifting to a minimun is obvious, but wether this is the case in any swing depends on the definition of "on plane" in the first place. That for me is the crux, the fundamenals behind the "chosen" definition of being on plane are still somewhat unclear to me (from a geometric/physics view that is). My feel/instinct 'get it' but the mind is lagging behind. mtr33 View Public Profile Send a private message to mtr33 Find all posts by mtr33
