i have all except for G.pulchra. both B.smithi and B.albopilosum flick hairs at me but of course i keep my distance so the hairs dont actually get to me (either that or im not affected by the hairs). both of my g.rosea have never flicked a hair at me and i dont think G.pulchra wold flick hairs either unless it really wanted to. for the chice, either G.pulchra or G.rosea.
