I would mount it on the front mate, do your fishing out the side and back like most do.
Get a spring mounted one too if you worried about a fish pulling you line over it or it hittimg as tree, spring mounts will bend then spring back.
just read you post, better if you casting on the front put it on the back, or and make a mount so you can change between front and back (some kind of clamp), it only a bit of wire you could do it if you wanted to.
cheers
