The dremel technique isn't the new idea mentioned in the post. What is novel is the use of the scoubi tube to mount the popper. As mentioned in the post:

"Rather than using a (big) hook I insert a length of Scoobie tubing through the centre of the body a la tube fly, this keeps the weight down and puts the hook right at the tail of the fly for those tail nippers."

This has the same benefits as other tube flys. I'm also thinking that a crease fly may be suited to this technqiue as well.
