You should go and teach Edd Sorenson then, as it seems he's unable to make them work. Same with Netdoc who's gone with "I'll just add a bunch of weight on the tanks".Took me one dive to setup AL tanks with my hollis. If it takes dozens of dives for these people you see, maybe they don't need to be diving sidemount.
Not dissing or hating any of those 2, just something I've noticed... Now you can go and clame that is a proper setup, but it's not, it completely defeats the purpose of neutral tanks.
