Colby clinched a league and cup double on Easter Saturday after ending the brave challenge of Braddan.
The southerners added the GH Corlett Woods Cup to the CFS Division Two title they won a week earlier, with a 2-0 victory at the Bowl.
The champions were pushed all the way before two goals in the final eight minutes from Furo Davies and James Cain secured more silverware for the Glen Road side.
