I tie most of my Tube flies using a Regal Revolution rotary vise. When I first began using the Pro Sportfisher Flexineedle to hold my tubes, I secured the tool with the vise jaws at an angle, and this is the configuration you will usually see pictured in You Tube videos and articles.
At some point I can not remember, I figured out that if I cut off a few inches at the back end of the Flexineedle, I could secure it in my vise with the head parallel to my fly bench. Doing so allowed me to rotate my vise and tie on all sides of the fly, including the underside of the fly.
I wanted to share this technique of shortening the Flexineedle in case it becomes useful to you, and wish everyone good times at the fly bench this and every season.
