I guess what prompted my question was seeing images of the bulletman suit. The oversized headpiece is there to presumably protect the head from impact. But I can imagine that by wearing one there would be techniques that I would hesitate to try because of it. For example, how would I attempt to tackle someone while wearing such a large headpiece? Wouldn't attempting a tackle while wearing a bulletman suit make it much easier to defend?
This got me thinking to how much the suit might limit the movement of the attacker(s), and as a result does the suit itself place the attacker(s) at a disadvantage? Maybe that's a necessary restriction for safety, or maybe it's something that you adapt to after you've worn the suit long enough, or maybe it's part of the progression in this type of training. Don't know...just thinking out loud.
