Hi Pete. You should use lemon oil on the fingerboard. Olive oil will build up a greasy deposit that will get very string-unfriendly.

Ovations are very bad for round fronted men because they wobble thier round backs around on the round fronts. They may be better for women lucky enough to conform to teh cultural preference of slim stomach and large not too wobbly wobbly bits, as they will sort of snuggle in without any sharp edges.

But if you are after the sound, buy for the sound.
