Actually, stiching them back together in Lightwave is a piece of cake. when you mirror one side, you make sure you'r cursor is exactly on the x "0" center. The polys will be mirrored and the points along 0 "x" will take the same places in 3d space. a simple "merge points" operation with merge them, but in lightwave, if you select "merge points", it'll do that automatically for you. The UV map can drive people nuts though, because it'll only show 1/2 the figure, and they will be tempted to paint on the other side, but that texture information, will of course not be used. Course, that's assuming you are working on a figure.. if it's somthing mechanical, or inorganic, in many cases you really do want mirrored UVs. Plus I'm finding Poser's biggest resource hog isn't polygons, it's texture maps. If you are wanting to go "all out" you might be using a color map, a displacement map, a specular map, and a transmap, and if all those are 3000x3000 that's a LOT of memory being used. If you can cut that in half, and still retain the detail, that's a good thing.

Way too many people take way too many things way too seriously.
