I have had several different dubbing twister all of them have done the job but this thing just does it better. Great tool for the job.
I recently took a fly tying class on dubbing techniques, and this tool makes spinning dubbing loops a breeze. I was spinning dubbing in no time at all. Even the instructor was impressed with this tool. A must have for dubbing "buggy" nymphs.
This is a quality tool. I should have ordered it ages ago.
OK, first, the instructions did warn that the tender thread would be a problem (my words). I found that less then slick thread, and/or tender thread would indeed break. Normally it would break at the hooks.
I found that the hooks had rough edges on them. It appears as if it is from the paint. I took my rotary tool (aka Dremel) and used the fine tapered stone to work the edges. I then used a tapered ceramic polishing stone followed up with the polishing felt tip and red rouge. It did a good job and unless you have a heavy hand it works as well as advertised in every way.
With most giving this a 5 star rating, it is apparent that only a few are rough, but, if yours is, and you have the tools, and are careful, the above method will work for you. For very fine or tender thread I still advise you use one of your old favorites from before.
I'm not an expert however the tool works as advertised
