Well interesting. I read your blog. I'd say, those equipments were pretty expensive, and I couldn't find any plausible reason for small timer to buy it. And yeah, a bit troublesome specially when you're doin' something else besides gambling, I mean you're not totally locked out with such helmet and just free to do something. Might be interesting for some, but as other says, it is not quite practical. But don't get me  wrong, this is still good for new experiences  .
