Heli- Muddlers are a go to pattern for me for just about anything that swims. Your variations are great. They will be a definite addition to my arsenal!
Brookie- Great soft hackles. Really nice clean ties, and I'm sure the trout will love them! Good luck with the foot healing, and since you have some time on your hands, I'm looking forward to more!
TTL- A nice little spey you tied. As you mentioned, shorten the wings, but shorten the body as well. Spey bodies generally start at about the hook point then go forward. Additionally, regarding the wings, as mallard can be a difficult, even more so on smaller ties, try doubling up the slips. Take a strip from the right and left feathers, twice as wide as you want your final wing to be, place one on top of the other, square up the tips, force a fold down the middle and tie it on. Works wonders for the wing set and is quite durable.
Rick- I just put the Pheasant skin away and now you post these beauties! Great ties, and fishy as can get! I have a dyed black Golden skin that would work nicely for the black variation. They're like a more elegant wooly booger, which we all know is really the only fly you ever need!!
I was going to post a take on a trout sized Atlantic pattern called the Branchu, but Photobucket does not seem to be cooperating tonight. Have to try again later, I guess.
Thanks for the great ties and all the inspiration,
