Would anyone happen to know - and please don't go to a lot of trouble to
find out - which option would be cheaper:

1. Using my Oyster PAYG for everything today, except a single journey from
Victoria to Clapham Junction that I have to do for which I would buy a paper
ticket.

2. Buying a Z1-4 Travelcard and using that all day.

It's a little hard to say without knowing more details about
"everything today", but I can tell you that Oyster PAYG capping, and a
Victoria costs 50p less than the equivalent Travelcard, and a Victoria
- Clapham Junction single is £2.40 - so the chances are, you're better
off with a day travelcard.
