For journalers who use fountain pens I would recommend the Rhodia “webbie” or the Quo Vadis “Habana”.
I use regular old Moleskine with my fountain pens. However, I only use the recto side of each leaf. This reduces the data density so I can find stuff more easily and it totally eliminates any bleed thru or ghosting. I buy my molies in bulk at clearance sales so I’m not really concerned with getting the most words packed into each volume.
