Why cut your chances of success to 20%?
That would be like catching the fish of a lifetime, and some bigger fish eats all but the head before you land it, leaving you only 20%.
I seriously dought you only put 20% of your real talent into tying. I bet you have a passion about it and that's why you sit down to tye.
So for the sake of your efforts, why not find what you really want and not compromise?
