Zanny I have found planar to be the most useful, but cubic mapping and cylinder cap come in useful as well. The thing is to use uv mapper and experiment and see what you can do with it. The pro version has a texture checker feature where you bring up a grid and preview your map choice against the grid. This lets you check how the grid maps on your choice of mapping and you can try different map options and see how it affects your model. I know it seems like such a pain in the ass to have to do all this manual mapping when Bryce procedural mats are so much easier, but this way I can put a rivet or rust spot or squadron number right where I want it on my models. If you look at the map for the camera model on my website note that I used planar mapping for everything on the model, except for the hotshoe for which I used box mapping and polygon stacking. I know that I am no wizard or guru at this stuff, but I feel it lets me do more than I could without it and I hope I can help someone else who might be wondering if uv mapping could help them do what they want. The good thing about this is you do not have to use all uv mapping in Bryce. You can mix and match. You can use the procedurals and perhaps just add a uv map to get panel lines or rivets where you want. You are not confined to using only one or the other.
