you can see riser flex especially at the top of the window, where the pcoket attaches, at the point of closure at the 1 min mark.
you can also see the longrod holding its position.
but you can see the root of the longrod taking a bit of load mid power stroke and especially during closure
from 3min on, you get to see quite a bit of rotational movement in the riser.
at 3:11 you can see during the power stroke the back side of the window twist out. showing bow induced torque.
you can see the top pocket twist as the bow unloads and the shock of closure. makes that top pocket shake a little
little bit of video i found that i thought interesting
