why should I go DIR ?

Al is on the right track. Your panicked buddy is going to grab the reg from your mouth anyway. If you have a system and process in place to deal with it you may be in better shape.

Also, it would be nice to hand your panicking buddy a reg you know is breathing properly.

Backup regs never stay in place -- especially at night while going through the trees. If you bungee the backup you know exactly where the backup is located. Less task loading = greater safety.

I should note that the long hose and bungeed backup isn't a DIR invention. I think DIR simply popularized it in the rec world.
