I have to second that sentiment (or third it
). Those plates look kinda teensy. A lot of us need to tweak the templates. Personally, I have to take the general width of the XL, but make the length from top-to-bottom somewhere between medium and large, 'cos I'm short and stocky.
On topic of the collar; if it's properly sized, it's going to limit your arm movement somewhat. To reach across, you sort of have to bring your arms down to sternum or stomach level. Or, you could do what some of us have and segment the collar plate. It still holds to the standard look, more or less, but adds that little bit of extra flexibility.
