Any of y'all ever try the Catalina AL 20's in their breathy-machines???
I ask because I really like the ass-light effects of AL tanks but want more gas than the 13's provide. These 20's look stumpy so I think they'll fit.
Cheers
Are they older tanks? All I see around are the 19's... Are they too tall? I assume there is about a 3 or so pound difference in buoyancy from full to empty for both tanks....
