Claims made about ascending vertical vs horizontal

The effect on offgassing is probably negligible. Being in a vertical position underwater just feels weird and somewhat uncomfortable...

You need to have more fun with unusual attitudes (in the aeronautic sense). One of the best things about diving is that we are actually flying, it's just that we require a denser medium to do it in than birds and airplanes. Enjoy the three dimensional freedom

Exactly, i can (have to) be upright all day long, only underwater can i fly
Especially in a drysuit, it's like laying in a hammock.

I'd rather be slightly negatively buoyant on ascent, and use my legs to propel myself upward. That's pretty difficult to do if I'm horizontal.

Relying on my legs to go up vs. keeping my BCD perfectly trimmed means that I can breath freely and completely without pooching my buoyancy. I don't mind kicking gently on a safety stop nearly so much as I mind an uncontrolled ascent.

This is a buoyancy and trim skill issue. There is no reason you should be kicking up and flapping arms to stay at your deco/safety stop.

I'm going Tiger Shark diving in Maldives at Fuvahmulah with a good dive buddy friend that has dived there before.
I am wondering what marinade I can soak his wetsuit in as I will be in shorts and T shirt mostly.

Night dives with Tiger Sharks sounds like a lot of fun lol

I dived there this year. It's a fantastic experience but I would highly recommend freediving/snorkelling with the Tigers. They get much MUCH closer, and it's a more visceral experience. If you freedive you will be on a group of 1 or 2 with a guide. The scuba experience was the opposite. There were 20 or 30 divers in the water so the guides make everyone hold onto a rock and the Tigers are quite far away. It's done like this because it's an easier way to manage a large group of people. Even if you don't freedive, you should try the guided snorkelling with the Tigers. You will be in 3-5m of water with huge tigers and you will be a matter of inches away.

The claim is that ascending vertically prevents your tissues from offgassing “evenly” rendering your stops completely ineffective.

"Completely" is an absolute. People who write or post things should have warning labels if they think the world is black and white instead of shades of gray.

This is nonsense. Horizontal trim makes sense when you are moving horizontally through the water because it minimizes drag and keeps your feet away from surfaces and other divers.

The picture came to my mind that if drag wasn't an issue, it would be fun to be propelled around while in a vertical position. But then, the bottom is where interesting things are, so back to horizontal!

the closer to the surface, the faster I spin.

This sounds dangerous. Wouldn't you create a vortex at some point? It could result in bad things coming down.

Speaking of dangerous, long ago, before I foolishly bought the pitch that college and a professional job is better than working in the field, I was a young EMT arriving at a lake to look at a prop injury. It was easy to conclude that I myself do not want to have a prop injury.

It appears that you have an overly active imagination.
