I'm fine at showing people best routes to use on the Underground but
does anyone have any ideas about the most useful ten/twenty bus routes
to learn?
The ones I know well are, 279, 253, 29, 8 (plus 25 and other local
ones) TIA


Generally, I find the most useful routes are those that link other transport
connections - e.g. rail and tube stations, without duplicating them.

From a South London perspective, my personal favourite is the 270.

Mitcham (Tramlink)
Tooting (Thameslink),
Tooting Broadway (Northern Line)
Earlsfield (SWT?)
Wandsworth (no good public transport)
East Putney / Putney Bridge (District Line)
