When it comes to weights, Justin, these facts & figures are from the Faber website:
Size Lightest Heaviest
3 3.4 3.8
7 7.6 9.1
10 10.9 12.4
12 12.8 15.2
15 16.4 18.6
So the lightest twin 7s will be 15.2kg, the heaviest 18.2kg
The lightest 15+3 will weigh 20kg, the heaviest 22.4kg
When it comes to bouyancy, the differences are:
15+3 light = 1kg positive
2x7 light = 1.2 postitive
15+3 heavy = 0.9kg negative
2x7 heavy = 1.38 negative
So your lead requirements will be pretty much the same, but the cylinders will be 4-5kg heavier with the pony route.
In terms of size, I've checked my own twin 7's against a 15+pony, and found them to be the same width and less height - so twins are unquestionably the smaller setup.

That was my first thought too, and so I bought a pony.
After discovering it was a rig I couldn't actually lift without a buddy to help me, I was delighted to discover that my twin 7s can be swung up with ease, even with all my lead bolted to it as well!
I hear a lot of negative things said about twinned 10s - generally down to them being too short for comfort. Have never tried them myself tho.
If twin 7s do have a downside, it's that you're unlikely to get two dives out of them unless depth is on your side. This doesn't usually cause me any problems, but it may be a consideration for you..

Well, I use a Buddy wing because it was good quality and cheaply priced. Wings like the DR Classic are popular, but probably too big for a small twinset.
I have a 1-piece harness, wouldn't even consider breaking it, as I've become very fond of the feeling of security you get from an unbreakable harness - I had a clip fail on me once, it's reassuring to know it won't happen again.
As for regs - whatever you use at the moment should be fine, just add another first stage. I got myself an Apeks DS4 when I went over to twins.

Where else do you need?
