How many dive cylinders do you currently own ?
About 20, including the ones two of my kids use. Some of these are made up into twinsets. A few are stage cylinders.
I have 4 cascade cylinders on my compressor. I also have a couple of oddball cylinders that are mainly useful for inflating tires, and a couple of SCBA cylinders. And one 3cf cylinder that I use when soaking regs.
What is the advantage of owning that number of cylinders ?
We use them for shore diving and have our own boat. We can spend a weekend at a remote dive site where air fills are not available.
If you had unlimited funds (but not necessarily unlimited space), what would be the ideal number of cylinders you like to own ? Why ?
In general, we dive four types of cylinders:
1. LP72s, which we use for "typical" dives.
2. HP120s, which we use for somewhat longer dives.
3. Twinsets, which I use for non-decompression solo dives at depths greater than 30 feet. I have several sizes but the HP100 twins are the most useful for that.
4. Stage/pony cylinders.
If it were just me, I'd want to have maybe a dozen cylinders -- two twinsets, four HP120s, and four LP72s, and maybe a stage or two.
