I would throw in there is no right and wrong with rig tying , lots of people will do it slighly different to try and change from the norm, to add that little bit of change to what the fish are used to,
as long as the basics are close most will satisfy your needs
i May aim to tie three rigs the same but all will differ, weather it is length of hair, length of overall hook link, or with ot without tubing , blowback ring
have fun and try out something new, you may find the next super rig for your water that everyone else wants
