No problem on the picture thing.... I've got a lot of people who call me up and ask, do I really look like the drawing, and I always respond "Drawing?? That's an actual photo from Glamor Shots!"
As far as lift vs. tank - really doesn't matter... sorta'. Let's assume your using an aluminum tank and wear 10 lbs of lead... It's just with a steel tank, you might only need 6 lbs and the tank is slightly more negative.
One of the main reasons for more lift is the amount of air you're carrying. An Aluminum 80 is holding about 6 lbs of air. Not let's assume you have 2 steel 120's so thats 240 cubic feet of air, which then will weigh 3 times as much, or 18 lbs. You will need to weight youself so you can do a safety stop when these tanks are near empty, and that means add 18 lbs of weight to compensate for the air, so at the beginning of the dive, you will have to use 18 lbs of lift - just to counteract that extra weight. So would 35 be enough for that?? Maybe... depends on what else is going on.. Hang tanks, wetsuit, dry suit, other options.
I've found the 35 lb bladder works out great for recreational diving, teaching, etc. And while not a techy myself... any of our instructors or customers that are, use more then the 45 anyway... So I'd say go the 35 - and you can swap it out to a big birtha bladder later - or if going real tech, you'll probably pick up something specific for that later.
