If I'm making a piece with no parameters, and just going by whatever details I want, usually I look through my stocks and the first one I find that nice, I mould stuff around that (so yes it takes little time). But when I have other things I need the stock to work around, (like speech as a theme in yours), then it is harder. Plus I'm a bit OCD, so I need to find the best for the piece I can get. :P
