This might make me reconsider a helmet mirror. I've wondered if I might improve my situation by using a larger mirror farther away from my eyes. This lets me swivel my head slightly to get it farther out and around my bulk, but with similar field of view. If you look closely at the photos of the VT mirror on the Amazon site, the flexible arm is made of coolant delivery hose made by Loc-Line. If I need to lengthen the arm I can buy additional segments for $6/ft.

Is the VT mirror convex or flat?
