Do a search for "Miflex" here. There have been a number of reports of their high pressure hoses suddenly failing, and at least one case of a low pressure hose suddenly failing, all relatively early in their service lifetime. Personally, I don't see a benefit that outweighs the track record--millions of dives--that standard rubber hoses have going for them.
That'll make pretty good reading, but not compared to all the material you'll find if you do a search for "air2". Yes, you'll lose a hose. Was that hose really an encumbrance? Consider different hose lengths and routing as alternative streamlining strategies.
Then, if you still have leisure time, do a search on "wrist vs console". I am pretty agnostic on that one, but prefer my gauges wrist-mounted.
