I have Faber-Castell Polychromos the whole lot, a few Prisma colour and a handfull of Caran D'Ache.
I haven't used any of them for quite a while although pre Copic that was all I used.
Perhaps this year I could try to use all my art equipment!!
I normally use the pencils themselves to blend using the lighter colours to blend over the darker colours, on the rare occasions that I did use a blending agent I use "Art Spectrum Odourless Solvent"
