Really happy i found out about yak hair. These yak minnows have been killing on the beach for both snook and tarpon and even managed a redfish on them. Its a stiff hair which helps keep the fly from fouling but once we it becomes softer and has great movement to it in the water. Sheds water so it stays light and easy to cast. Definitely going to be incorporating it into more patterns. Only thing you need to look out for is getting natural yak hair vs synthetic yak. The synthetic yak doesn't get soft like the natural so it has less movement.
