A WB is not a bad investment. To me it's just one less thing to worry about and you only lose about 5 fps. When I'm closing in on a muley there have been times when I thought I was ready for a shot and knocked an arrow just to have the deer move and I had to take a few more steps. It's not far enough to take the arrow off the string but far enough you have take a few paces so half of your concetration is on keeping your arrow in it's place. For me it's my pointer finger pinching it in place. Then you hit a small branch or obstacle and instead of focusing on the deer you are looking at your bow to put the arrow back on the rest. A WB is a nice way to eliminate that problem.
