The projects are looking great. The branch LR your using are going to look pretty incredible once encrusted...I know what you mean about trying to ship the big pieces. A while back I did a project like this and ended up with several huge pieces that are now finally starting to encrust, problem is they are too big. I had to move one of them to a tank thats at one of my retail stores and the blasted thing would not fit in a 5g bucket, finally had to use a a cooler lined with bags, make up a bunch of water etc........

If you ever need to ship something like that, use Southwest Air Cargo, it's an airport to airport shipping method. I order stuff from LA at 9 in the morning and it arrives around 2-3 the same day. You could ship a 5g bucket wrapped in insulation and then inside of a box for maybe $60-$100 depending on how far. It's just a pain to ship this way as you sometimes have to sit around and wait for goober and his cohorts to figure out how to open a door without hurting themselves, serious..
