Either that, or the headache excuse.Do tell? Do they also complain of the sub-clinical DCS symptoms like heavy fatigue?
I didn't read it that way at all. I see it more as an adapt and overcome course of action. I do marginally prefer 100% as well. Having access to only 80% will not stop me from diving. Even further, if I have to choose between full tank of 80% versus a 100% tank filled to 2/3rds I'll go with 80%. And more than a matter of cost it's a matter of convenience. My closest gas supplier is not the cheapest one.I find this comment a bit out of character. It sounds like you're advocating letting someone else make the decision on the dive plan and you're just going to follow along?
Why? Even a AL40 of o2 filled to 2/3 will last a solid 20min of deco. That's more than enough for most dives, and if it's not, you're boosting He anyways.I didn't read it that way at all.

Similarly, I dive a BP/W the vast majority of the time. I do still own a BC jacket and will use it very occasionally. If during a business trip, the schedule changes leaving an opening for a dive, I have no qualms about using a BC jacket. My belief that the FJ Cruiser is the most capable vehicle out there because it can take me to places lesser vehicles won't, will not prevent me from driving a Chevy Malibu rental when I'm traveling. I'll probably won't take the Malibu off roading, but it'll serve its purpose of transporting me.

Maybe for you. Some of us go on more serious dives.
More gas gives you more options both below and above the surface. I feel more comfortable using a full Al40 for 2 dives. I may not have enough gas to comfortably do 2 dives if the Al40 was 2/3’s filled to begin with. Having a higher left over/initial pressure comes in handy if you want/need to transfill something on site. Earlier on this thread I posted about transfilling left overs to squeeze in a last recreational dive during stat holiday when no dive shops where available.Why?

How serious are you getting without access to a booster?Maybe for you. Some of us go on more serious dives.
I suppose, but by getting 30% more gas you're also going .3ATA deeper, so you're raising your consumption and the gain isn't quite what it appears. I can see your point, but I'm guessing there's a very limited selection of dives where this is a benefit.More gas gives you more options both below and above the surface.

Answer- you're not.
