Found.

I've been trying to find a good enough paper to ink on. So far i tried Marker paper from Canson, Bristol Board from Daler Rowney and W&N. Daler Rowney worked best but the ink bleeds a bit so my lines aren't sharp enough. Suddenly I remembered my stash of about 100 sheets of 250g Schollenhammer drawing paper. Sheets are 45X62,5 cm so i get two A3 out of every one. Gives a really crisp line. They have a yellow tone but works OK when scanned.
