In reply to Michael MacArthur:
Portland: basically nothing - the few remaining Trad lines are esoteric in the extreme and almost exclusively single pitch.
Swanage: various Traverses, some already mentioned and most "up" routes in Boulder Ruckle, Guillemot Ledge and Cormorant Ledge are climbed in 2 pitches - the routes tend to be 35 - 40m in total, so pitches are fairly short, you're guaranteed an adventure though.
Expect committing abseils, steep climbing, juggy roofs, pumpy cracks and walls along with some loose rock and the occasional scary top out (scrabbling up steep earth/grass desperately searching for the salvation of a stake).
