Flopped set against villain taking weird line pre

[TheGreenMile]

im guessing my hand is too transparent here, but i dont know how to play this in this pot. The first limper was a habitual limp/folder, so that contributed to me raising pre. i had no idea what oo make of the BTN's re.. he is 19/7/2.5 and seems pretty inept at hand reading.

is bet flop better? check/raise more? i thought this way he was pretty much committed..
