Is there a single outstanding choice? Never! It's large bulky crap no matter how you slice it.
Right. I think we're living on different sides of the planet with different normalities.
In the UK 232bar is normal with only steels available at 300bar. Those are our HP and LP. 300bar is still considered a bit freaky in some circles.
I had a 300bar twinset and the view that it was strokey and I'd never get nitrox or trimix fills got boring as I was doing it routinely.
I went for 7L stages in steel having had to trash a set of Alis that I was given as they needed expensive 'extra' tests due to being an out of date material. Also they were 207 bar. Steel is just steel. I liked their slightly
negative at all points characteristics so they stayed down rather than finding the rear ends bobbing up under my arms and getting between me and things I might want in a hurry (valves). Also they were noticeably physically smaller for the same internal volume.
I'd go for personal choice but somebody offering a reason that I didn't understand perked my interest.
thanks.
