Where are the serious solo divers? There is a way / are ways to manage the added risks to solo diving....lets hear about it. Or we can kill this one and I can go solo diving through the archives...

I started diving solo regularly maybe a year and a half ago. I had logged a little less than 200 dives at the time. (BTW up till now, I have never been seperated from a buddy, even during dives in 5inch visibility, so no unintended solo dives.) Before that, my first one was at around dive #40 in 1994. I remember the nagging doubt I had the whole time because I was doing something 'forbidden', and I felt a little vulnerable. However, my max depth was 50 feet, and this was where I could freedive to, not to mention that the site was very familiar to me, so the added risk was probably very small. At that dive alone I saw more fish than maybe 5 other dives combined at the same place. I also covered maybe twice as much ground.
I didn't dive solo for the next six years, and when I did it again, it was at a site where max depth was 30ft and no rough conditions. After a couple dives, I realized that diving solo had its own merit, so I started to think about how to make it safer.
Among all the risks, I was chiefly concerned about three things.
1. Regulator/tank failure: although it is a very rare occurence, this could be potentially very bad. So I use a 19cf pony tank for dives below 40ft, where slow ascents become more important. Above that, I feel that direct ascent to the surface is an acceptable escape method, and is within my ability. (I can breathhold swim horizontally maybe 120ft with fins, and can freedive to 50ft.)
2. Entanglement: I carry a knife and a shear, and I make sure I can remove my rig underwater if needed. (This means that I also don't have integrated weights, as this will make me overly buoyant once I have the rig off.) I also never venture where there is bound to be monofilament. As for kelp, I am streamlined enough for that to be little more than an annoyance at most. I found that good awareness of where my body parts/gear are in relation to surrounding objects is key to avoid potential entanglement situations.
3. Lost/damaged mask: This is actually the one I used to worry about the most. How would I be able to do a controlled ascent without a mask when I am solo if there is no bottom contour, line, or wall to follow? If those three or a buddy are available, even the blurred vision and touch will be enough to get me to the surface safely. If they are not, I would be in trouble because I can't read the depth gauge and my ears are the only indicator of depth change, which is too coarse to be safe. Reaching the surface would be easy, but whether safely is another matter. I thus decided that if I would dive solo at depths more than 40ft, I needed a backup mask. I now carry the mask in my drysuit pocket, and since I have it anyway, I just carry it on every dive.
There are other things that I am worried about, too. Now that I think I am somewhat prepared for the above three more plausible failures, the thing I worry about most is a shark attack.
ut: If I get attacked and am injured badly, a buddy may be able to get me to shore in time, but if I don't have a buddy, I'd be in pretty bad shape. But then again, there has only been a handful of shark attacks in Monterey on divers since the early 1900's.
In order to dive solo, one should be completely self sufficient, be meticulous and also be in good shape. One should also be very comfortable underwater and should be able to calmly take care of any problems that may arise.
Having a good buddy does reduce the risk even more and usually enhances the enjoyment of the dive. But sometimes, I prefer diving by myself, because I want to devote my attention wholly to enjoying what's down there.
