As a side note, the Paraloop is similar to the Hackle Stacker, but they aren't exactly the same. The Paraloop style of tying is slightly more versatile as the hackle loop can be varied in size. I got the book Tying Flies the Paraloop Way by Ian Moutter at Christmas and enjoyed reading through it. With that said, I have yet to purchase a gallows tool and have been limited to tying Paraloops which are 99% identical to Hackle Stackers.
