I'm a car wash mitt guy. I've tried all the brands and colors and are down to two colors: green/chartreuse and tan/cream. I got a tan mitt years ago that I still use (one mitt makes lots of flies). I few years ago the cream RainX car mitt mops were all the rage so I got one. Not sure if cream or tan is better. Both look like crane fly larvae to me so I can feel like I'm matching a real bug. I usually start with a tan mop which I think looks more natural (especially in clear water), but some days chartreuse is what they want. Mop chenilles are OK but I got a lifetime supply of tan and chartreuse ones from a mitt so I am done experimenting.
I do much like the above with a size 10 jig hook with usually a 3 mm black bead. They seem to work just with the mop, but the Ice dub collar (bronze peacock, peacock, black all seem OK) makes it look better to me to fill the space behind the bead. Tried tying on hackle collars and putting an egg up front like the Mop and Glow fly. However, they didn't work for me any better than simpler flies, so I only do simple ones now.
