WBs are great for stalking because the arrow won't fall off the rest. If you only treestand hunt, then I would go with something else just because the WB will wear out and as it does things change. My thought on drop-aways is that it is one more moving part and every moving part will eventually fail. I know that is an overly cautious way of looking at it but better safe than sorry. I use the old school two pronged deal. Simple, effective, and when stalking I just have to use my index finger to hold the arrow on the rest. Just my opinioin here. Probably won't even be read.
