Ya know, I kinda went through that same thing last summer when I built that
behemoth Study 5 of the bridges,
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=232218 (hey, I only used
6000 2x4's); life's little annoyance of having to order stuff and then
ripping apart the model when you get them (All those 1x1's were a royal
pain!) The trick is knowing where it's worth to do the overlapping

Agree, with walls, it can be much of a pain. Esp. if you KNOW you're doing
a zone that's going to be subject to some degree of change (could be a
little, could be a lot) and one hasn't quite reached the "Final answer?
Yes, final answer." stage.

Well, I'd like to add overlapping when building columns isn't much of an
overkill, esp. large ones. Those that I've built for bridges I can
transport much the same as a wide tube. Generally, I don't put in cross
beams within but prefer to just keep it hollow; it's a good, well thought,
overlap that'll do it. I've found if you use a clear, managable pattern,
you can easily calculate the exact number of bricks needed to whatever
height you're aiming (makes those LD and BrickLink orders easier).
One more area where you DEFINITELY want to some serious overlapping are
curved or arching structures. One thing I told myself when I built Study 5
was to avoid the use of plates w/ the exception of the edge railing on top.
By that, if I had used plates in the arch, I would have violated the prime
directive. I'd say much of the overlapping there came out a winner.

Yea, just think before you do!
