I have the MST Equader full zip jacket. Mine was a Cabela's bargin blind deal with a zipper that doesn't always like to work (comes unthreaded).
That being said, that is the only issue with it, and I haven't heard of that being a problem for the majority of them. It's very warm, and fits well under waders. While it wasn't a particularly colde year, I hunted throught the entire season last year, and on most days it kept me warm enough to eliminate the need for a coat.
Overall, I love the design, and fit. As far as 1/4 vs. full zip, I think it comes down to preference. Same with the camo choice.
I don't think the ducks will mind if you have MODB up top, and Max 4 waders below...
Sounds like you have found a deal that I would highly recommend.
