If I remember right the 999 is their biggest seller so you can't really go wrong, but I'm no Pete expert. There is a good chance a pipe cleaner won't go all the way through as it's a bent Pete, but I'd simply go down to the b&m with a cleaner and see for myself. They won't care. Check the drilling and if it talks to you snap it up. If my local pipe shop has the pipe I'm after, so I'm able to check it out beforehand I'd be happy to pay extra for that.
