i've been using si tubing for the last year, i think this evaporation argument is overrated. i don't have the feeling i ever have to add water between service jobs (6months). there might evaporate some, but it sure isn't enough to make my room smell like antifreeze.
although it isn't clear, i like the way it looks.
got some tygon recently and will be mixing tygon and si in my next setup soon.
joe, you'd care to elaborate on those advantages?
