I used to use Beinfang paper primarily, it does have a nice texture, and seemed better than some of the "cheap" sketchpads I'd tried out. IMO, it's a nice middle-of-the-road paper, better than cheap paper, but not as nice as some of the finer art papers. It is a little light for graphite if you work in layers or apply a lot of darks, but makes a nice pad for sketching. Also, it has more grain and tooth than a lot of papers, which can be a good thing. I've come to like smoother papers personally, but everyone likes something different.
So far, the drawings I've done on Beinfang paper have not yellowed or shown any signs of age or damage. I would suggest working with a better quality paper for drawings, but the Beinfang paper will get the job done.
Hope this helps.
