Hi
I make a lot of my own spinners and have had a lot of success with them. I suggest you look at Mortac. They are out of Granite falls (have a web site) and also some of the shops like Ted's and 3 Rivers carry the parts. The blades are thicker/heavier than Viberex and get down better. I have also heard of people taking Viberex's apart and making them heavier. Also take a look at their Stilly spoons. They work well on Coho
