Re: dark montreal??
I know that this is an old thread but I just couldn't resist talking about the Dark Montreal.
Yes....it's a great fly and brook trout find it irresistible. However, do not use red but use the colour called "claret" which is a wine colour....a deeper colour than red. I also use this colour when making Royal Coachman dry flies.
I may even tie a few dry flies that are similar to the Blue Wing Olive or even a caddis imitation but use claret for the body colour.
