Question for all you experts out there . . .

I will be in London for a week and in the past i would just buy a tube
pass for the week. Is there a better travel card if i planned to use
the tube a great deal? I might take the bus now and again but the tube
will be my main transport.

I'm hardly an expert in these matters, but I think I'll chime in anyway.

On my recent three-week visit to London, I started off with a Z1-3 week
Travelcard, since I was traveling around a lot and ventured
semiregularly to Z3 (I was staying in Z1). But after a few days, it
occurred to me that week Travelcards are priced for commuters, while I
was generally not embarking on any Tube trips before 9:30, so, if I
instead used pay-as-you-go, I'd be eligible for the much less expensive
off-peak daily caps. So after that first week, I switched to PAYG, with
off-peak day Travelcards for those days when I'd be riding National Rail
within the zones, and I ended up saving a bundle.

Without more details on your travel habits (which zones you expect to
typically travel in and how often you plan to go outside them, how early
in the morning you leave, whether there are some days that you don't
plan to do much if any riding at all, etc.), it's hard to give you a
precise answer. MaxB has given you a pointer to the definitive source
of all information regarding fares, so you can run the numbers yourself.
