Kokopuffs, that sounds worth exploring. I get e-mailings from King Arthur Flour, and so I searched their site. They have a silicone-coated, heavy metal pin:
Blue Pastry Pin
Sur la Table also has the silicone/metal pin (except for some reason theirs is red). They have one with tapered ends (it's purple). I found the boxwood one, but the price is pretty steep. Its weight may be more than I can manage, too.
Any thoughts on the silicone-covered pins? I'm learning a lot about the world of rolling pins!
