Two strobes vs one big one

I would be interested in hearing your opinions on the merits of a single ds125 vs a dual ds50 strobe set up?

DS-50 |vs| DS-125
Size 8cm x 12cm ~ 3.2" x 4.7" ||3.75" x 7"
Weight 0.6 kg ~ 1.3 pounds||2.75 pounds
Energy Rating 50 watt-seconds||110 watt-seconds
Coverage Angle 70 degrees||90 degrees
Color Temp 5700 degrees Kelvin||4800 degrees Kelvin
Power Source 4 "AA" alkaline||NiCad batt
Flashes 200 Full Power||150 Full Power
Recycle Time 3.5 seconds||1 second
For 1.5 lb and 3" more you get a much better strobe.
If you do mainly macro, then twin DS-50 would be more useful. You will hardly ever need the power of the DS-125.
If you do a lot of wide angle stuff in nice clear water, then DS-50 will not have the penetration power for the sweeping shots. Two of them will cover the angle, but not the depth. This will also result in a lost of depth of field. Then a single DS-125 will become more useful.
You still can do macro with a single DS-125, but if not controlled properly you can get very strong undesirable shadows. Not saying shadows are no good, but sometimes you do not want them in the picture.
To do it all, then twin DS-125. You can lower the power setting for macro, and still do nice wide sweeping shots.
What kind of shots do you normally take, and what kind of affect do you like, will dictate the equipment you buy. No point buying a macro setup if you always go for sharks, manta's, big coral heads...
What happens if you like both macro and wide angle, but no money? Then get a single DS-125 for now. Later on, get another DS-125.

I agree with David, though, I'd go with the bigger strobe and buy a second later. One big strobe does a lot for me, but then, you might do macro or have a reason to really want two strobes.
The battery packs are a consideration that you shouldn't overlook. The smaller strobes can rely on the same charger and AA nimh's as your camera, which can mean more redundancy assuming you have a couple chargers and plenty of batteries. If you don't, you are setting yourself up for a single-point failure. The bigger strobe has it's own charger. I have an ikelite 200 (same charger, different battery pack) and though I hate carrying it (I am already carrying two AA chargers and lots of AA's), I love the reliability and power.

As for me, I am still waiting for my Canon S40 housing to come in. Then need to wait for the DS-125 to become available in South East Asia; currently it is only sold in USA.

I think the TTL works well. I find that people who criticise TTL exposure metering usually own a Canon or an Olympus...

Descisions made. I have ordered the Canon Powershot G2, and Ikelite housing with dual handles, and two DS125 Strobes and sensors.
Whew, hopefully Ill ahve enough saved back up by my July Cocos trip to add the Inon W/A lens set.

Best of luck, hope it all works out for you.
For me dive trips come first, equipment second. So collect the equipment I want bit by bit over the years. If a trip gets cancelled (normally due to work), then I splurge on the gear.
