Im going diving this coming Monday (EXCITED!) and am an air sucker/newbie. My girlfriend uses almost no air. My dive instructor suggested to use 100's and have her stay on the 80's, might get our bottom times closer together.
Anyway, I emailed the dive operator who replied that he had some 100's I could use but that they were "much" heavier but no more negative. (So I'll have to use the same amount of lead).
My question is how much heavier? (Could he mean his are steel 100's versus the aluminum 80's? If that was the case steel 100's would be much more negative than an AL 80 wouldnt it?)
Also, with the extra weight but no more negativeness, will I just expend more energy swimming with them and negate the extra bottom time?
So which one to use is the question.
