I disagree, I dont think using Hen hackles is a guarantee to catching more fish, I have been using snatchers a lot longer than some and have found genetic hen hackles are to fragile and come away from the body very easily with both the teeth and hook removal, yes they may be a fraction more mobile but when campared I have noticed no difference in catch rate when up against the saddle hackle which is also far more durable and will still look as good after 20+ fish as it did after the first. I had been experimenting with snatchers for 10 years before I did my magazine article in TF in Feb 2004 and the feed back I have had from both other tyers and customers who have purchased them have showed that the Metz #2 cock saddle hackle is more than up for the job in both barb length and mobility as it is softer more of a Heny-Cock type feather compared to it's rivals, Hebert Miner, Keogh, Whiting etc. Hebert Miner and Keough are to long with very stiff stems whereas Whiting barbs are far to stiff and again have very hard stems. Again these are only my findings and are not gospel, if you are using a stiffer, longer hackle and you are catching fish then stick with it, after all confidence is a great "fish catcher".
