In the wetland area I spend most of my time in, I use Judo condors. To match my heavyweight broadheads, I take a rubber blunt, cut the end off and trim it until it weighs out right, turn it around backwards, and put it behind the Judo. It works better than a washer for two reasons: 1) It doesn't catch an edge and bend my (aluminum) arrows, and 2) the wide arms on the condors don't kink when they bend backwards, like they do with washers.
I usually shoot clumps of grass rather than stumps. I hardly ever wreck arrows that way, and never have to invest time in pulling them out from being stuck, either!
