I forgot to add, if I feel that the pattern has to swim with a specific orientation, ie, the top has to be the top, I tie in a very small piece of foam on the top of the tube then add the materials over it. I have also tied some clouser type tubes, tied in the barbell weight towords the front and then tied in the materials, I only used enough tube to tie in then had the hook hidden in the materials. there is also a FOTW on here called the bunny baitfish. this fly is pretty much the same as mine but gives great tying instructions.
