I like the hunter green. This is more like OD green. The marsh grass is more of a mustard yellow/green. I have both colors on two seperate boats and much prefer the hunter green. That's just my .02. Choice is up to you though.
FME #28, Dead Grass Green, wears very well. nice classic color. Properly grassed up, I think any dull color will work fine though. They all look good grassed, with mud and blood on them!
