Yes..........but haven't dove them in maybe a year.... whenever I look at them, they look like two nice 'new' stages....:11:Betail:
How long before you started diving doubles?

I started on a BP/W and went imediatly to doubles. 3 sets lp120's, 1set lp 85', 1 set al 80n's. I cannot over emphasize the need for most divers to increase their lower back strength before going to doubles. You didn't say why you are interested in doubles, but it usually goes something like this. Doubles, then a stage or two, can light, scooter, camera.....damn this is getting heavy! The only good news is your wallet will be getting light at a very fast rate.
I feel like I should be making seperate threads for each of my questions!
Otto, like many others has a number of sets of double 120's, only they're low pressure steel tanks. It seems like he's trying to carry as much air on his back as is comfortable, so why not use high pressure tanks? This seems to be the case with a lot of you. ??? I know that 3500 psi and up requires a DIN, so I can see your logic if you prefer yoke, but I don't think that's your reasoning.

I find that they LP108 tends to trim me out very well in the water without the need for me to do any "adjustments" to my gear. I didn't have the same luck with HP tanks that I tried.
Also, in my area, I can get just as much gas in my LP tanks as others would get in their HP tanks. Though this is not true for many areas I am told.
LP tanks also seem to be more common near me, and are easier to get, especially used. When you are buying multiple sets of tanks, and are not wealthy, price is a major consideration.

The main reason I have LP 104s is that when I bought them, the HP 130's didn't exist.
Also, depending on where I am at, I treat my 'LP' tanks as 'HP' tanks. (gotta love N FL)

My LDS owner is cool when it comes to doing his best to fill my alumium tanks. He'll fill them while they're partially submerged in cold/cool water. Once they completely cool off after filling, they usually level out around 3000-3100. Is it easier to overfill an LP steel than an aluminum tank?

LP tanks are rated with a plus rating to 2640 psi. It is customary (not saying it's "right") to fill them to 3300-4000 psi here in N. FL.
Aluminum tanks should not be overfilled.

I did my OW class in a bp/w, and bought one right afterwards. I've been diving doubles off and on since ~ dive 40.
I have double 80s right now and am going to double up my 119s soon.

For doubles, using DIN is always a good idea as this is how almost all sensible manifolds come!
LP tanks are somewhat easier to fill with PP blending, the tradeoff as you say is tank size -- a LP120 is bigger physically than an HP120. Of course, an LP120 is also "equivalent" in theory to a HP-something --150 ?
EDIT: Also, LP tanks are usually cheaper as you can get em used more easily.
I can get a PST LP-80 for around $120. The E7 (or X7) 100's are more than 2 times that cost.

I started with AL80s. They were cheap and can be used with a wetsuit. Then I borrowed a friend's LP85s and loved them. I realized the size and weight were very similar to the AL80s, but they hold a lot more gas at with a good fill. When I realized that I wasn't using my HP-130 singles anymore, I doubled them up, too. They are nice for deeper diving and cave diving.GetNarc'd:
