Sorry, but I do have to take issue with those who think that this is nothing but a skills or weighting problem.
There is such a thing as heavy legs. In particular, people who participate in sports such as cycling and skiing tend to have over-developed legs with very little buoyancy. If you don't have them yourself, it's easy to criticize the problem as being one of overall trim, over-weighting and/or deficient arching/clenching skills.
Yes, these issues are important, and it is critical to have them dialed. If your legs are not too heavy, working with these may get you all the way to perfect trim.
For me, getting these issues sorted got me maybe 90% of the way to good trim. But it was still a lot of work to keep my feet up, so I'd break at the hips when task loaded, and my feet would drop.
Neutral fins solved the last 10% of the problem.
Gear can't solve everything, but sometimes the right equipment gives you just the extra "bump" you need to reach a goal, or increase your comfort.
I agree with you completely. I know you wanted to take exception to what I said above but we really agree.
There are two main parameters
1) how much weight do you need
2) how the weight is distributed
"heavy legs" do happen..... but all that means is that the weight needs to be distributed more toward the head. In the picture I posted, can you see where my weight is?
No.
I know where it is... but the result is that the trim is perfect. It's not all in one place.
I've said many times on Scubaboard that I could achieve perfect trim with my tank in a rucksack and using milk jugs for trim. And I could.
Why? because skills trump gear.
