Thanks for the compliments!
That fly is on the same hook style, but it's not weighted from the mold. I'll wrap some lead wire sometimes, but molding lead onto the hook would make it heavier than I want to be casting with my fly gear. I just like that hook because of the longer front section since there's more room to tie on. The hook under the fly, just shows the basic body wrap, and on that one there's no added weight.
They do work very well and no, spinning isn't a problem.
