Let me be the first to welcome you over from rec.scuba. And I am also 
impressed at Randy's high qualifications for his ex-employees.

As far as your rig is concerned the only problem I can see is that you 
are wearing your tanks with the valves on the top. Over here on TechDiver 
we only use the latest techniques. And in this case the Limeys, er, Brits 
have once again paved the way in practical methods and techniques and 
developed the proper way to wear your tanks, i.e. with the valves on the 
bottom.

This way reaching your valves is no problem at all. There are a couple of 
techniques to putting your tanks. If you are a lazy, fat slob you can 
bolt a bracket to the necks of your tanks so that you can put them on 
while sitting. But most Limey's, er, Brits are in excellent physical 
shape so they cut a "U" in seat of the diveboat and don their tanks 
whilst standing on their heads.

Also remember that another latest technique is to use flavored amoeba 
scuba guards to avoid confusion in which reg to use. According to the 
latest IANTD regulations you use strawberry for 02 and Banana for trimix. 
Or was that peach for 02 and guava for trimix? Definitely don't use 
Banana for 02 as this could explode... Randy, some help here?

So have fun reconfiguring and remember to try this new setup in a bathtub 
or jacuzzi so you will be ready for your "real" quarry dives.

>configurations. I'm ready to buy 3 complete tech diving setups (one for
>myself, and two for students to use). So here's what I'm looking for:
>
>1. Doubles: I'm looking for those really heavy humongous steel ones that
>hold lots of air (especially when overfilled). I'll also want some of those
>burst disks that won't blow, no matter how high the pressure goes (I think I
>can cut them myself from steel shim stock, but I'd rather buy them from
>someone who knows what they're doing).
>
>2. Manifold: It's really hard to reach the valves, so I think a manifold of
>any kind is a bad idea. Instead I'm going to train my students to use
>independent tanks. Then if there's a freeflow you don't have to worry about
>shutting the reg down, just switch to the good one (if you're not already
>breathing it), and end the dive when you reach thirds. You also have
>protection from a manifold failure that dumps all of your air faster than
>you can shutdown a reg -- I've heard about this problem. I wish there were a
>way to make the left-hand tank have its valve stick out the left side and
>rotate counterclockwise -- any ideas?
>
>3. Harness/BC I'll be looking for something like a standard ADV with lots of
>D rings added to it. I like soft cummerbunds and the ability to get out of
>the rig quickly by several different methods provided by multiple
>disconnects. Any ideas on how to add another bladder to one of these Tec
>BCs? I'll want two power inflators, O2 clean of course.
>
>4. Regulators: For each rig, I'll need one reg with a right-handed second
>stage, and one with a left handed second stage, each with gauges. I'll need
>a two BC inflator hoses on each (a total of four - primary and backup BC,
>drysuit, and bag inflator/airtool).
>
>5. Stage bottles: I've seen the DIR tape and I that think their way of
>attaching clips to the stage bottles is dangerous. That rope looks flimsy,
>and what if it comes untied or unravels in the water? I'm going to use steel
>stages, and weld clips directly to them. That way, the bottom clip can't
>slide around like they do when attached with hose clamps, and the top one
>can't slip off the tank valve. The clips should be the extra large gated
>snaps, because they're much easier to attach that the slide "dog" type
>snaps.  I'm looking for steel 72s for this, O2 clean of course, with the
>green bumper stickers.
>
>6. Stage Regs: Looking for just about anything. I'll color code them and put
>hose wraps on myself. On the high O2 one, I'll use either a little bag to
>cover it up or a piece of surgical tubing on the mouthpiece. I'll give the
>students ample opportunity to try several methods of coding the regs for
>easy identification. The high O2 mix will go on the right, and the lower
>will go on the right. That way, the student need only remember that the
>first mix will be the right tank at his left hand and at the 30 foot stop he
>should switch to the right tank near his right hand. Of course the left tank
>valve will turn counterclockwise with this orientation.
>
>7. Lights: Helmet mounted lights, five of them. The primary will be in the
>center and of 50 watt power. There will be two wide beam lights and two
>narrow beam lights. All will burn at the same time. This is the best way,
>because if one fails, you're not in darkness trying to fumble for a light
>clipped to a tank D ring that's nearly impossible to reach anyway.
>
>8. Mixes: I'll teach trimix using the poorman's 17% helium mix, but only to
>about 240 feet. This gives a narcosis depth of about 190. Since most people
>are good on air to about 220, that should be good. I'll give them a checkout
>dive on air to 220 first. That will tell me if they'll be ok on the
>poorman's mix at 240, and will give them an appreciation for the mix. We'll
>switch to air for deco at the first stop or at 180, whichever is shallower,
>then to EANx75 at 30 feet. I don't want to use EANx80 at 30 feet, because if
>the students have bad buoyancy control and drift down to 40, they might tox.
>
>I'll also be teaching an "expert" deep air course. It will be really cool.
>For safety, we'll train in the pool, simulating narcosis, by smoking reefer
>just before getting in the water. Then we'll do shallow open water dives,
>reducing the number of bong hits as we increase the depth. Before you know
>it, my students will be experts at diving to 270 on air, without drugs or
>alcohol, and to intermediate depths either way.
>
>Boy, my students are going to be the best!
