Paper from Clairefontaine is recommended; it is available from good specialist shops and has also proved itself for breaking in old nibs. A further option is the refill of the Montblanc Diaries & Notes / Notes and Matters books (item 9526), which can be ordered individually at boutiques; the paper matches the well-known Montblanc test pads. Anyone who wants a custom-made blank book should approach a local bookbinder and supply their own high-quality paper if needed. Inks with high paper requirements feather quickly on soft writing paper, so firm, smooth, sized paper is preferable.
