what sidemount tanks do you dive with?

[Josh the diver]

What tanks do people choose to sidemount in for cold freshwater drysuit diving? I personally use faber HP 100s. I'm wondering if I should switch to LP steels?

older LP steel 72's. works great. tried heavy steels. hated it. then when in warm water i use standard allum 80's

My personal opinion, I only use LP tanks in diving locations where I can get cave fills otherwise I use HP tanks. Namely I use HP100s and LP85s.

LP50s or HP80s

ONLY use LP tanks if you can get them cave filled. If you choose to dive LP tanks and you aren't getting cave fills, I am sorry but you're a dumba$$. There is truly no polite word for it.
IF you can get LP tanks cave filled *at least to the same pressure that the HP tanks would be filled to*, then LP tanks may make sense. I personally use Faber LP121's as my primary sidemount tank. They're enormous and heavy, but in the water they get quite floaty when they're empty and are very similar to an AL80. I am big enough to use them comfortably though.

Since you are diving FX100's I assume you're looking at LP85's since they're siblings. With the LP's, you'd be 3lbs lighter per tank that will have to be replaced with lead assuming you are neutrally weighted. The only advantage in the water is when you are handling the tanks in front if you where the more neutral they are, the easier they are to deal with. Unless you're doing serious wreck penetration or squeezy cave ****, I wouldn't bother looking at LP tanks.

LP85 @ 3600psi holds 15% more gas than HP100 @3442.
If you can get cave fills (typically ~3800 psi) it does make sense IMHO.

where I fill my tanks the shop does not fill past 3000psi but I get free fills. I was looking at the LP 104s

doesn't fill anything past 3000psi? That's garbage. Why are you looking at 104's?

Yeah it sucks but it’s free. I was thinking 104s so I can have 100cuft of air or more if I can get them filled to 3000psi
