Gord, has Drury Lane set your geometry up correctly? No offence meant to anyone here, but all the courses in the world mean diddly if you use that learning to set up geo to the wrong figures. That goes for all the dogs danglies equipment too. I could use a piece of string, a spirit level and a torch to set up my geometry all wrong, with no courses at all ;)
I have no axe to grind with WIM, Drury Lane, TDI, Prolex or anyone else but I am sure getting tired of the bickering that seems to go on around the forum.
