Levi,
I have a large Devestator and just bought a medium Guardian. Both are awesome vest, but i do like the way the Guardian has the built in cut collar and chin flap. I usually do run a cut collar with the devestator, except for on my younger CD because like Chris said, along with a regular collar and / or garmin, it covers most of his neck. I usually just run the Garmin collar through the straps of the vest when its on the older ones. The cut collar just gives maybe another inch or two of protection on their neck. The Devestator has taken alot of hits from some good hogs, and the only cut that went all the way through was on the leg flap. Even being cut through, i think it saved Meathead alot of damage that would have been worse without the flaps.
I can run either vest on all 3 dogs, but on the large they are almost on the last holes for Diesel and Meathead. Either choice you make, you are getting a good vest.
Tom with the Guardian
Cant find a good one of the Devestator, but here's one of Meathead with the cut collar on with it, I usually run the cut collar underneath the neck part of the vest.
