The Boss Jack is a great vest choice, and although it's Swamp Rat instead of Busse Combat, the RatManDu is also worth considering if you want to go a little larger, but not too much. I'd lean more toward a BWM as a chopper with all-purpose capabilities -- it isn't as good a dedicated chopper as the CG BM because it's lighter, but I think it's a better all-arounder.
