I think I'm going to go with the Micromatic grommit, ferrules and hex nuts. Seems to be a solid (and the most inexpensive) solution.
BTW - sweet set up there Jason.
I bought the coils on Ebay for $80 each no bargain considering I'm paying $30 to ship them (total). Think I would have saved a little cash had I more patience and remembered the $7.99 shipping from various online homebrew stores...
