David, I'm still hit-and-miss with having 105 finish well. Sometimes it finishes so darn well it's amazing, other times I get major trails and holos. This is all with the PFW, btw.
It appears that doing a third pass before it flashes over really helps. Also making sure that you go over *exactly* the same area you went over on the first and second pass helps alot. If your second and/or third passes should overlap into an area that wasn't hit with the first pass, it really looks aweful; any area that only gets one pass really seems to look nasty.
Tricky stuff, that darn 105. I love it.
M95, OTOH, is just wonderful stuff if you don't mind taking the time to break it down all the way. The finish it leaves is beautiful.
