I've made a few prototype tube fly inserts for large C&F design boxes utilizing tapered brass pins that sucurely holds today's popular tubbing material. I am cosidering making tooling for a bigger production. Before I proceed I am interested to hear how many of you are willing to pay $55 per one insert, shipping included. One insert holds 18 flies. If things looks promising ill start shipping them by the end of January and ill be contacting speypages administrator to sponsor the site. Pictures will be uploaded shortly.
