I've tried at least 20 different papers over the last two months. I can honestly say that THE VERY BEST is staples 120gsm, and if you tolerate a slighly heavier weight the 160gsm from staples as well. I've been on a bit of a quest lately, and I've tried HP colour laser 100 and 120gsm, Claifontaine DCP 100 and 120 gsm, conqueror, Mondi colour laser 100 gsm, 120gsm, and 160gsm. I've compared smoothness, feathering resistance, and bleed through to both Rhodia and the Clairfontaine triomphe, and the Staples colour laser 120gsm and 160gsm performed as well if not better. It's also incredibly good value, with 250 sheets costing between £6.5-£7.5 depending on the weight you choose. The Staples100gsm was not particularly good so don't bother with it..
