Quo Vadis is an Exaclair product and the Habana notebook is reputed to be filled with Clairefontaine paper. I have used the QV planners in the past, and the paper does indeed look, feel, and behave like Clairefontaine - smooth, white, and FP-friendly.
Habana notebooks are not available in my town, but on a recent trip to Calgary I stopped at Reid's Stationers and picked up the 10" x 15" ruled notebook. This is really a larger format than I like to use, but it was the only size available in the store that day.
The Habana resembles the iconic Modo e Modo moleskine, with stiff black leather like covers (though slightly more flexible), rounded page corners, back accordion pocket, elastic, and bookmark - woven instead of satin. No big surprises there. What I really wanted to find out about was the paper quality - and here is where my experience differs from bluestocking, who wrote an excellent review here. The paper in my Habana does not have the silky feel that I expected from a Clairefontaine product. It feels more like the paper in my Mead composition book - which is good paper, for a $3 notebook. But the Habana is not a $3 notebook. It feels nothing like Rhodia, Clairefontaine, or the Quo Vadis planners I've owned in the past. It feels toothy running your hand over it, and this is confirmed by writing - I tested several pens and inks on it, and the worst was my Sailor 1911M medium - my smoothest nib by far. Writing on this paper made my pen feel scratchy - in fact, I had to keep some Rhodia notepaper nearby to write on intermittently to assure myself that the tines didn't suddenly spring out of alignment or catch a fibre. There isn't any doubt that it was the paper causing the scratchy feeling.
I am utterly baffled that as a clear competitor to the Moleskine, the Habana still fails to come out ahead in the paper department. Although there is less feathering and bleedthrough on this paper, the writing experience is made so unpleasant by the toothiness of the paper that one can hardly bring oneself to use it. I'm astonished that the smooth writing one would expect from the same company that produces Rhodia and Clairefontaine is not to be found in this product - and thus the Habana has no advantage over the Moleskine for me.
All that said - I find it interesting that bluestocking's Habana, presumably bought in the UK, does meet the expected standards. Perhaps inferior products were shipped to the colonies?*
If someone tells me "oh no, I bought a Habana in Canada and it was excellent, I would be inclined to drop Quo Vadis a line to ask if there have been paper inconsistencies. But for now, I have not been won over by this particular moleskine alternative.
*ETA: I noticed on bluestocking's thread that someone in Vancouver apparantly bought a good Habana. Hmmmph. Maybe they're shipping inferior products to the prairies.
