Seat post length

I'm going to buy a new inline seat post for my cross bike but I'm unsure what length to get. 99% sure I'm going to get a Thomson Elite. A 27.2 is required for my frame.

I was thinking that a 250mm would probably be correct, however that would leave less of the seat post in the frame than is exposed., so Im thinking maybe better to get a 330mm and cut it down if I ever need to in the future.

Any advice? What does everyone else use?
