Generally a 52/36 11-28 is sufficient for anything here in Belgium. 53/39 is do-able with a Sram PG1170 11-28, which has larger cogs, but only after a bit of training.
Compacts are just too spinny (for me) on the flats when riding in a bunch.
Yeah I rode a shorter loop last year on a giant defy with 52/36:11-28. The gearing was ok, but the trek weighs considerably more, and we are doing the full 235km course hence the 30 bailout cog
