Art, do you have a pointer to the polyester knit gloves with latex you describe - are they made by Atlas?
Funny thing, I walked into a Seattle marine supply store that outfits most of the northern fleet (crabbers, halibut boats etc), and almost every glove they sell is Atlas. I think some of their upper models are more than I need for light search and rescue, I think I want something like you have described for after hurricane cleanup. I think my little countycomm gloves will give way pretty quick, and my general purpose leather garden gloves don't let me grip anything too well.
