What issues? I have one of the earlier versions of his cards that has more texture and agree it does not slide great on felt, but it was not made with Fournier stock (forgot which stock it was). Fournier stock should be fantastic. One of his earlier iterations on Fournier are some of my favorite cards and I think they were made circa 2012 or something. If that is the issue I think it has much more to do with the cardstock than aging.
