Bronson Arroyo or Bartolo Colon ?

I need to add one pitcher for WINs and Ks.

Colon is on fire but has faced Seattle 3 of his 4 games.

Arroyo was a HR machine last year (worst in MLB) but seems to have righted the ship and has much better lineup backing him.

I'd much rather have Colon. Just be sure sit him against the Rangers and AL east.

Who else is available? I'm not big on either except for streaming against top matchups and/or two-start weeks (in weekly lineup leagues).
