I often spin worsted weight! Great for hats and other little bits. I had the fine spinning kick a few years back, but I can't knit very well with laceweight yarns, so mostly now when I spin fine, it's to 3-ply into a fingering or sport weight yarn, for socks. Still have my little ball of froghair though, and still have some spindles and fibers I like to "just spin fine" on. Kind of meditative.
