Bruce, backside – backside tailslide.
This photo was used as the main photo for a Terrain Spotting at the recently built Girlington Park in Bradford. Bruce struggled with this back tail for a while before doing it, which I guess shows how challenging the bowl is to skate. After he had worked out the lines in this bowl, we got a couple more photos in quick succession.
I think you really have to see Bruce skate in person to understand how good he is, but check the recent Sore promo or the Team DC KOTHM edits for up to date evidence.
