I had no idea until I stumbled onto this thread, after 3-4 hours reading through the forums.
I like the full length blades personally, but I think the option of simply ordering a different size blade is a good idea. After all WE all know you can just request it in the order comments, but someone who isn't on the forums and just stumbles upon US and doesn't know this might want a 30" blade or something, and doesn't order one because they think they can't get that.
