Ah right. I use spun poly and the only downside to it is it soaks up so much water. I might have to try the braided nylon at some point.
if your spun poly soaks up water its not spun poly, for this very reason you cant dye it. Its coloured in the manufacturing stage before its spun, nylon will soak up liquid and can be dyed after manufacture

bought all my spun poly from agouti over about 2 years which is who everyone seems to recommend for poly so Im sure it must be the genuine stuff. It does soak up a lot of water though.
