Does no one use slings?
I've played a gnoll once. RMSS Races & Coltures - Underground Races contains a racial TP spell list for them, which adds some nice spells for the sling stones. That was fun. Other than that I had a dwarf paladin that used the sling as secondary weapon. That was okay because the sling allows for usage with a shield, which makes up a bit for the slightly worse attack table of the sling, compared to e.g. a composite bow.
