Ok, I get ya, the swinging parts are the main concern. Have you tried the sam brown studs on other parts, like where the back of the cuirass and front come together on the shoulders. I don't know if the buckles I used where too large or wht but when I added the pauldrons to the one in the pictures he complains that any strikes to the shoulder hurt. I'll probably make him a gorget and attach the pauldrons to that to allieviate that problem, but I'm getting ready to make another one for a younger kid and was wondering if moving the buckle that joins the front and back further towards the back rather than right on the shoulder might be more comfortable, or even if the same brown studs would work, just further towards the back as well.
