you're really hell bent on my posting my profile pic. don't like taking the extra effort to make that one mouse click to see it?
ever been in a net? I used to dive around lots of them, 100's of hours. been wrapped up in a few. it's no picnic. now I dive in the tick kelp beds of BC's coast, another place where hangups are a constant issue, although just an annoyance in comparison. a slung bottle is under your arm, your shoulders break the current and you arm/elbow generally protects the valve (the only real hangup area) for tanglies. if something does get hung up on it, it's right in front of you to fix. low task loading. ever watch videos of the tech guys on their scooters, and where their stage bottles sit while they're in forward motion? hmmm.
so while I'm comparing our two rigs at your request, you're twice as likely to get something caught on your back, requiring you to remove your gear.... oh wait, but there's the posts from your yoke-style regs too! make that 4x, and then there is the wedge point between your main tank and bailout.....
but hey, who am I to argue with the internet experts. everyone has their own level of risk they're comfortable with. I'm done trying to teach this particular pig to sing.
