Because the WB is more forgiving/easily/faster repaired if damaged. Also no strings to catch on limbs and such. Accuracy is plenty good with my WB setup for hunting 3 quick kills last fall + one turkey so no problem w/accuracy here. No worry about arrow falling and spooking critters. Yea someone mentioned freezing rain, but that would effect a drop-away as well. Besides that would be a rare exception but can be dealt with in either case. As for fletching it doesn't matter what you shoot,fletching will somehow get damaged with either setup. So far the WB on my bow has not been the cause. It does appear the drop away-may be a little more accurate, but that margin would probably be more helpful in 3D target competition vs hunting because a 1/8" or so could mean the difference between a 10 or a 12. When your that close in hunting it does not make a difference, it's still a kill shot. Since the accuracy is very good with the WB I opt for simplicity and ease of repair and use.
