I tied on an HMH Pro for a couple years and I still do use it for my largest and smallest flies. The interchangeable jaws for for the large and small flies just can’t be beat. If it wasn’t for the Griffin Montana Mongoose, I’d still be tying on it everyday. HMH has just posted up a video on how to properly set up your new HMH. I wish it was around when I first started tying with one. It would have sped up the learning curve.
