Nick, I first became aware of MOAL flies when I spotted a picture in a catalog. Since then, I've investigated other flies I've seen, such as Intruders. I've never fished for Salmon or Steelheads & may not likely ever get the opportunity. But, I will take note of flies that I feel bass will like. Those Salmon/ Steelhead guys are all nuts when it comes to new styles, and they come up with some great bass flies without even knowing it.
When I first started tying, I came up with a new fly tied with a palmered hackle body & a long hackle tail. It looked killer, and I was real proud of myself. Back then exposure to tying & fly patterns was pretty much restricted to magazines & a few books. Then I received a copy of an Orvis catalog. They were prized for the nice pages of flies they contained, and I discovered that my new fly had been around for some years. I was a little bummed that I had not invented something new, but at the same time happy that I had tied a known productive pattern on my own without being aware of that pattern. Made me feel like I was thinking as other tiers, with more experience might.
That fly turned out to be a Seaducer or Hackle Streamer, a fly that I've now been using with great success for many, many years & one of my all time favorites.
I have some similar flies that are tied with marabou, purchased from a guy who sells flies on Ebay. Cannot be sure how they compare to what you've tied, but I've not had any casting problems or fouling issue with them. If you do have some issues, might be that you'll only need to tweak them a bit.
I'll be looking forward to hearing the results if you get the chance to use it.
