So what is everyones preferred method to bulk up the profile with flies? I have been tying for about 1 week, and almost never follow rules. This may be a bad thing. I normally see a fly and just try to tie it while reserching techniques online. Has anyone had expirience using the soft discs from pro tubes? seems like the easiest way to maintain large profile flies. As of right now i have tried spinning dubbing in and or clumping arctic fox. I feel like i waste so much arctic fox in the process. i only really tie on pro tubes is there any disadvantage to this?
