Cool. The LI system I've read about as being good. The Laser Pro Park dealer is somewhat close to me, and I was considering going with them, as a friend who's got it, is happy with it. Did you research them too before buying? What did you think?
Do you know if the LPP system uses diodes too? Or LED's? Read that diodes are better because they're more powerful...
I came across this link also discussing vertical vs. horizontal mounting on the LPP forum basically saying vertical worked when they tested it, but for worst case scenarios, it could leave some gaps:
