I assume that its driven by availability but it appears that no one follows the original recommendationsfor oil specs, which puzzles me. 
It clearly states in my handbook that my LM2 wants 10w50 in the engine and SAE90 in the gearbox and bevel drive.  Yet everyone and their dog seems to be sticking 20w50 and 80/90 in respectively.
Now I'm willing to be slapped down at this point, but I'm currently stuffing Motul 5100 10w50 in my engine (thank you Opie)
I personally prefer the advantage of the tiny bit of extra cold start protection but I seem to be out on my own here. Am I doing my engine a disservice

I'm sure for every owner you find using 20w50 we could find just as many using something else.

I always used 10w40 myself in the SPIII.

No it won't make a blind bit of difference to your engine, though it might to your pocket if the 10w50 is more expensive.

You also have to remember that the Guzzi manual was written a long time ago and oil specs have changed and improved since then.

Ok ta
I figured in the years since the original manual was scratched onto a wax tablet that advances had been made in the oil industry. 
I also figured that in all the years since my engine gasped its first breath, that bitter experience may have taught us to ignore particular recommendations on that wax tablet as they lead to certain ruin.
As I said in my 'Hi all' introduction post,  apologies for stupid questions and faux pas but I ask anway and hope to leech off the wealth of experience and knowledge of those on here patient enough to put up with me

No such thing as a stupid question.

Modern sythetic oils have been known to creep past oil seals more than the older mineral based oils.

That's certainly my experience with an 850T3 (of which I am the current custodian) which is, I'd guess, of similar vintage to your LM2. I've tried various oils (within the recommended W range), and it's abundantly clear that - on this particular machine - the less synthetic the oil, the more it stays inside the metal bits. As I have got a 'classic oils' dealer practically on my doorstep, I've decided to go with the flow (see what I did there?).

I read, (somewhere, a while ago) that engine oils with grade above SG don't lube enough to prevent flat tappet engines wear so to prevent the evil eye I add a ZDDP additive.

And I read the oil companies claiming that they had other additives which made up for the ZDDP.

The Leifheit 72582 8379 has a dreadful squeak, I use Duckhams straight 80 to restore domestic bliss.

Have you thought of changing the foot rubbers for a softer compound

Interesting idea Dba, but i've since found the real source of the squeek.
It's my elbow.

I was going to suggest you put some of your Figs under the ironing board feet but as it's your elbow you could try there.
Just the one though.

True.
You have to be careful with figs.
I have a strawberry tree with fruit I'm told make you go a bit squiffy.
I haven't tried it yet.
