JD It lenghtens the draw and aligns bones and joints. You are completelly different morpohology than me, tall and wirry, so you draw differently than me, but you can get all the working elements in one line.
Take a look on picture of me with that long draw in my "tutorial" thread.
I m first to admit there are far better longbowmen than me, but I did a good deal of work about "how to sqeeze most perfomence out of really small machinel" and you dont really recgnise how tiny I m untill I stand next to normaly sized person. Hahahaha
I like that dynamic release you do, but once you start to level on any sort of target, or even on clout type of target, youll find out that very solid stance is needed and you probably go lower in knees. The "jumpy jumpy" part is funny to watch though
