Texposed is just like the Texas rigging of a worm except that you expose the hook point all the way thru the worm. On a senko on an EWG hook, the hook point and the end part of the hook is laying on top of the Senko. You can also push the point back under the skin of the hook a little bit to improve the weedless feature of the bait. With as much plastic as the Senko has this improves the hookset since you don't have to set the hook through all that plastic.
