I use both Arches 185gsm & 300gsm papers in rough as I find my style - impressionistic - is emphasised by the rough surface allowing all brush strokes from wet in wet - moist to damp - and dry, to have maximum impact. Pigment distribution within the surface is one of the great features of this paper thus allowing for granulation when the paper is angled. This allows for pigment to run downwards and distribute throughout the shape in a professional manner. I always use Arches papers for all my work. Best choice.
