WSU, the Magnus Stinger's are an excellent choice for your wife's arrows! They are a true cut on contact broad head, will get exceptional penetration and cause maximum damage, and fly very well out of a tuned bow. I would opt for 100GN BH's for her arrows (two blades w/bleeders so I guess you'd call em four blades) to maximize arrow speed out of her 50LB draw weight. Only problem I see is that she's close to not meeting the WDFW minimum total arrow weight standards w/BH (300 GNs). You can tinker with a few things on the arrows and get em' up to 300 grains though. Happy hunting to you and Mrs. WSU this fall!
