I agree with the UK1 attack on Toburk, its got a very strong chance for success and is a major setback for the Italians. I would hesitate to do all those attacks at once with the UK, might over stretch yourself.
Omega, I dont see whats wrong with having 6 or more tanks sitting in London by the end of UK2. When I play as the UK, I usually go heavy turttle with them, and wait till the Germans are at war with the Soviet Union before making major offensive moves. On Uk1 I will buy 9 infantry, saving 1IPC, attack the Italian fleet in sz95, using the UK fleet in sz98, the fighter from malta, and the cruiser from sz91. Then for non-combat I move the fighter from Gibraltar to London, I bring the infantry and tank over from Quebec to London, if possible, if not, it goes to Africa and the destroyer in sz71 moves up to sz81. I will usually fall back from Alexandria, leaving a lone ANZAC trooper, and hold up in Cairo until I see how Italy reacts to my opening move, and I begin the march up from South Africa, and from India towards Persia. Also, depending on the situation, I’ll move my transport from sz98 to sz99 with 1 infantry in it and activate Greece, just to be a nudge. This gives me 12 infantry, 3 fighters, and 1 tank in London and allows me to collect 36IPC on the end of UK1. On UK2 I buy 6 tanks, the fleet in sz95 should have been reinforced by the French forces in sz93, provided anything was left for them to reinforce, and I will move the remnants of this fleet to finish off the Italians, reinforced by the destroyer from sz81. Again, for me its really hard to predict just what I do on UK2, manily because I really need to see the situation before I decide what to do, so anything beyond UK1 is a guess. However by G3, when sealion is usually attempted, the German player is looking at 12 infantry, 3 fighters, and 7 tanks in London, and a rapidly crumbling Italy, which I think would give him pause and make him redirect his economy and forces towards other fronts.
But then again, thats just me :-D
