Faber LP 95 or Worth X7-100

[FWADIVER]

The downside of HP100 is that you will likely be overweight when you dive the river in summer in thiner undergarment

yep, everyone I know that have HP100's are looking to get rid of them for LP85s or LP95s because of this. the 100's are less versatile, too heavy for sidemount, never get a good fill at the quarry etc etc. In all honesty I've been pretty much talked out of ever being interested in HP tanks at this point, they just seem to be more trouble than they are worth.

I sold my HP100 set for all those reasons. HP100 as doubles is probably one of the worst tanks for fresh water.

To the OP - I would really consider getting Faber LP85 set instead of those two you are looking at. It trims well, more buoyant than HP100 so you can move the weight around and your rig will be balanced.
Anotehr option to consider is Luxfer AL80 they are great for the summer in the river. A bit heacvy on the surface though.

I use my HP100 All the time. I always get good/proper fills even at my quarry's and dive shops. I dive dry all the time also so I have yet to be overweights just because of the tanks. If anything you will be more over weight with the LP95's since they are 1) Heavier when empty, 2) the are more negative when filled, 1/2, and empty in water. So to say that you would be more over weighted with the HP100 vs the Lp95 is not correct. Now the LP85's are a little less negative in the water but weigh little more on land but also have 17% less air on normal fills.

I don't dive Sidemont so I can not speak to that. But unless you have specific issue's where you know 100% you wont get a fill over 3000PSI then get the HP100's. Most shops can and will fill these to Spec. Again I have been and gotten my tanks filled from about 6-8 different shops and gotten them filled correctly I also get my yanks filled from the quarry's in my area with out issue.

The LUxfer80 is a good tank, But you then have the Issue of Less air and then you need to add more weight due to the fact that Alumim Tanks become Positive by 3.4lbs at the end of the dive so you need to dive over weighted to counter this.

Here is the info you need:

Steel Cylinder Specs: XS Scuba Hangers
Aluminum Cylinder Specs: XS Scuba Luxfer Aluminum Scuba Cylinder Specifications

I have two Luxfer AL80 and two PST+ 72 at the moment sitting in my garage.

The problem is that I dive with people who dive Wet while I dive Dry. I used more air due to the drysuit and also my SAC is abysmal.
Last dives in quarry I had to signal back because I was the first one to reach 50% of my tank's air. Got to ascent marker at 700psi, got to 15ft stop at 500psi and surfaced with 400-380 psi.

I checked my team's and they had 900 psi, 600psi and another with 400 on LP95's which would compare to 600psi 80cuft.

I was also looking at the option of having a pony tank for drysuit air. But I don't know if I'll be comfortable having another bottle strapped on the side and being unbalanced.

I wanted bigger tanks to just have a hassle free and clutter free system. The pony bottle setup is like 350$ or more. Which is as much as a new tank.

I'll try another time with the Luxfer 80's and I'll how I do and if it's again the same i'll check it out.

Thanks for the tips

It is to bad that we don't live closer together. I have 2 faber lp 95's that I am offering for $ 175 each. But 400 miles roundtrip to the Albany NY area is a haul. I am not likly to be headed north to the Valcour area of lake champlain untill july or so. I am not sure how easy it is to drive across the border with tanks as I have only crossed the border with tanks via boat.

Sincerely nitrodiverrr

If anything you will be more over weight with the LP95's since they are 1) Heavier when empty, 2) the are more negative when filled, 1/2, and empty in water. So to say that you would be more over weighted with the HP100 vs the Lp95 is not correct. Now the LP85's are a little less negative in the water but weigh little more on land but also have 17% less air on normal fills.

HP100's go from -2.5 empty to -10 full with valve
LP95 go from -1 to -8 with valve...

I think you do not have your information correct. The OP mentioned it's a Faber LP tanks, not Worthington. Fabers are less negative than worhthingtons and in fact LP85 is lighter on land than Worthington HP100, it's dry weight although can be more whan you add extra lead.

You have to consider that the OP is living in Montreal and local diving happens a lot in the river that is warm during summer time in 60-70th and it is a fresh water. So what works for you not necessarily works for the OP as the conditions are different.

A lot of people dive Aluminums here adding just 11 lb v-weight to the double set. It makes the rig easier to balance.

I would say based on the fact you have probably as many dives as I do just wait, as you get used to diving dry your consumption should go down, heck my SAC got cut in half just by changing fins. I had heavy jet fins and switched to dive rites, I didn't realize how much I was fighting the fins to stay horizontal and went from surfacing with 700psi to surfacing with closer to 1800-2000 for similar dives.

Try with the luxfers you have before spending more. You might find that they will be enough for you for some time. Your SAC will improve once you feel more comfortable in the suit.

I'll keep going with the Luxfer.

Thanks
