I'm not using the pack function with overlapping UVs anymore as Brad (the author) explains above, it can cause problems.
Sorry, I don't see how I would get planar mapping to map 2 strips on top of each other; besides the 2 strips can be on different planes.
Camera mapping I haven't used - I'll have to experiment with that.
Anyway, today I actually managed to get things to work the way I want! :)
I used Brad's suggestion to map the strips on top of each other. Then I had to do some additional vertex/UV welding and everything seems to be OK - i.e. no unnecessary unwelded tris! Phew, it's taken me ages to sort out that prob.
