I don't know about the person who does it on this site but our woodcraft accepts anytype from slims to bullet pens to barons. I think it depends alot on who is sending them and where they are going. I know we sent some to pilots in Germany and they loved the bullet ones.
My understanding is they will take anything for the troops. I prefer to do slims, European and of course Creeklines. A good question to PM Gary who is overseeing this project...
