Hey Eric--

Different dubbing materials and threads don't react well sometimes. I find most synthetics are tougher to dub than natural materials--that's just the way they are. I know that a lot of it depends on what the dubbing is made from. I would say experiment a little if you can. Try some other sythetics that aren't as "coarse".

Also, make sure you're only applying small amounts to the thread--smaller amounts than you would normally use with natural dubbing. Applying thick balls of synthetic materials to the thread is frustrating, and while it takes longer to tie a fly, small amounts are the way to go wind on, and stay on better.

On the other hand, some people like the "buggy" look of synthetic dubbing so don't be too harsh on yourself--you may be making the fly even more attractive to fish :). . . Check in at Generation Wild in the next week or two. I'm going to post a vid on how to tie a cadddis larvae and there's a bit about dubbing (coincidentally with a synthetic material). Hope this helps!

Try prewaxed thread or use roll on glue.

If its a nymph body try a dubbing loop, or sometimes your thread can even be split and then add a little bits of dubbing in the middle, sping it until it secures the fibers and wrap in on.

If its a dry wax is good, but not to much, just enough to grab the loose dubbing.

Also it take practice. I used to use wax but with the correct pressure between your fingers and thumb you can dub anything onto the thread with out wax.

one more tip, keep researching, learning, and experimenting and you'll do great stuff and catch big fish with your own custom flies.

try using prewaxed thread AND wax together. twist the dubbing on until it is really thin. it should be about as thin as your thread you are using.

I would suggest applying less dubbing than you think you should. Benromans is absolutely right.
