I am trying to make this simple for him Wayne.
Of course one can use a line pick for collisions, but it makes things more complicated, and I have never encounted the problem you refer to with regular collisions except when dealing with Bltiz terrains. (The morphing appaears to screw up collisions.)
I had to choose one method to describe, so I chose the simplest one, which I use myself, and which works for most things perfeclty fine. :-)
