Any reason for a newer diver not to go with a streamlined setup?

[No2rdame]

I'm looking at going with a streamlined regulator setup where the primary is on a 40" hose routed under my arm with a swivel at the end and an octo on a 22" attached via a necklace holder. Are there any reasons not to go with this setup, apart from it's not the standard and you'd have to share your primary? Being that I did my OW dives and a few rentals with an integrated air source, the idea of sharing the primary is not that big of a concern and would just involve making sure any dive partner knows the setup first.

Main reasons I'd like to go with a streamlined is simplicity and, obviously, streamlining. While the integrated air idea is nice, I'm looking at Deep6 regs and would like to keep both my primary and my backup the same manufacturer for servicing purposes.

There is absolutely no reason not to do this and many reasons why you should.

Sounds legit to me. I always think that the short hose should be bungeed around the neck. Just be sure to use two of the same seconds.

that, that's all you need.

You already trained primary donate with the air-mcdoodle so the only difference to you is getting a much nicer regulator from your neck vs. trying to find the air-mcdoodle dangling from the mile long hose that it's attached to

That's my setup exactly!

New diver here! Did just that. No regrets. No issues, no snotty comments from other divers too!
All good.

I find 22 inch is too short for the back up, 24 is better for me.

I'm sure plenty of equipment manufacturers can think of a reason why this is a terrible idea: You'll be happy with it the first time and won't want to rebuy everything!

Sounds like I'm on the right course, then. When I started researching the streamlined setup I was shocked it's not more common. It's just more intuitive to me, but then again maybe it's in part because I was trained to donate my primary anyway. It also seems much easier to have both my primary and octo right in front of me rather than having to reach down to locate the octo. And to @tbone1004 , I'm going to have to borrow the phrase air-mcdoodle.

The only question I have, and this may be a complete non-issue, is whether having your octo below your chin ever restricts your head movement?

@No2rdame I stole it from James Mott of "The Great Dive Podcast" so I can't claim it as my own.

on the restriction, it's a non-issue, nothing to worry about. When you tuck your chin all the way, the mouthpiece is supposed to be right there at your mouth. No restriction whatsoever
