To me it doesn't change a thing to have a twinset without the skills or a single tank. If anything, you're safer with more gas.
I don't buy into the "you'll go into deco and die", you can get into deco easily on a single tank. Worst thing that could happen imo is that you get out with 160bars in your tanks.
I personally find a soothing point to the knowledge that if you a lot more gas than required. Much more enjoyable than thinking "damn, will I cut other people's dive short?" imo.

Slow down, take your time and get a lot more experience before even contemplating a more complex setup. You can get a lot of good experience with a single AL80. When you're ready, get properly trained on all the aspects of diving with doubles before trying it on your own.
It is more 'technical' .... doubles is more than 'is my gas on?' kinda thing....
Do you need formal training? Not necessarily, but it does make sure you are completely squared away in a day. Something like GUE Doubles Primer would be a great course with very little pre-requisites:
Else, look to your LDS if they offer tech training. Make sure the instructor dives doubles on a regular basis (many do other configurations, which don't equate into doubles ... sidemount, single with pony, etc)

Great question!
There are 10 possible failures on manifolded valves (just getting gas past the first stage) ..... and many ways to think you are ok but not ....
You learned how to switch and donate regulators off of a single tank in OW. I'm guessing that is a "Total Rubbish" skill?
By your reasoning ("Total rubbish again"), learning how to switch and manipulate manifolded valves are much simpler and don't require any thought at all then ...
So, what is rubbish about suggesting seeking some guidance about how to use some specialized equipment? What would you suggest to all of us?

You can donate in the same way. There is no need to manipulate valves. And if you can't work out how to put your arms behind your head you should probably not leave the house let alone enter water.
The op could treat a twinset as a big single quite happily. There is no need for training to do so.
I do wonder how people survived before these courses came about??? It's a total mystery that so many older divers are still alive.
I never took a single class to dive doubles. Seriously, it is not rocket surgery. You do NOT have to have a 7' hose simple because you are in doubles. The only RULE I would say to someone just wanting to dive doubles as a big ole stable lots of gas platform in recreational dives, ISOLATOR OPEN. Thats it. You actually have real redundancy with doubles and with very little work from the OP it is a much safer platform to dive. Band you up some AL80s and get on with it bud.
