I bought one of the original, less packable, version after researching with busy guides (who weren't anyone's "prostaff") favoring them for durability. Some guys on these boards knocked them for having pins they struggled with, but that was easily remedied by anyone with a drill and half a lick of sense. I found it as advertised, but didn't use it much and eventually gave it to a friend.
Again, however, it wasn't from the current generation of SUB.
If you think I'm wrong, you might be right.
