Did a test fit last night with one arm prior to putting elastics in. After being referred to the reference pics and priceless guidance I've caught a couple of issues. I haven't removed enough return edge on the inside bicep so my hooks are going to have to come back out and some more scoring, snapping, and sanding will have to be done.
The other issue I have is that my elastic on my biceps are too tight pulling my bicep up and creating a 3" gap between my hand plate to my forearm plate.
Many kind thanks Tony!
