Byron,
Kudos on your flies. They looks great.
Your are correct in that the dun/emerger paraloop has no wing case over the hackle. However, other paraloop patterns do use a tied over thorax.
Chapter 10 of Ian Moutter's book, Tying Flies the Paraloop Way, shows Jim Cramer, a member of Flyfish@ at the time of the fly swap. His version of the Borger Braided Butt Damsel uses the paraloop hackle with a pulled over thorax over the paraloop hackle.
It was Hans Weilenman who put Jim Cramer in contact with Ian, and I think Jim got the idea for the braided butt damsel from the Flyfish@ Fly Swap.
Other paraloop patterns do have the thorax tied over the paraloop hackle. This is how Ian ties spinner patterns, crane flies, and other patterns that have splayed wings.
Regards,
Silver
