I am running a Bravo I on my XD 21. B&B'd by Robbie Patterson. I have not made a wfo run as of yet. The holeshot is terrific and has little or no bow lift coming out of the hole, a real plus in skinny water. It pulls strong up to 80 mph. It has some more but I don't have that speed bug anymore. It's 30p x 14 1/2 on 300 PRO-MAX.
