Compared to allot of wing chun alans stuff is light years ahead, theres contact movement and so on as for arm punching one thing Orr is known for is the power of his guys hitting, they used to put people down in MMA fights with just body shots, his guys win allot through Kos and TKOs Honeslty it looked like close range unattached fighting you see in allot of MMA guys, you dont get that much footwork at that close a range, looks like they were trying to stay in the pocket as much as possible
