Overflip and Underflip are really mistleading names. I think a flare is a backflip and a 180. We dont call 2.5 rotations in a pipe a 1080, we call it a 900. Therefore, a backflip in the pipe would make you land switch. Flares are a backlip 180 in a pipe. Therefor, all backflip 180's can be called flares. Simple. Its a switch flare.
