The White and Orange Clouser is a great pattern when UK Saltwater Fly Fishing for Pollack and bass. For the UK waters , a 2-3 inch length clouser has been very productive. If you find that a lot of small pollack are being caught with the smaller clouser, switch to a longer length clouser which will cause the smaller pollack to snip at the tail of the fly without hooking, giving a better chance of one of the bigger pollack to take the fly.
The clouser is tied with a dumbell or bead chain eye on top of the hookshank. When cast, the weighted eye(s) cause the hook to be reversed with the hook point upwards above the hookshank.
With most clousers, they are tied with a two colour combination. White is usually the main colour along the hookshank and the secondary colour is tied as the underwing. When cast. the secondary colour moves to the top of the fly and the white colour to the underneath.
Clousers can be tied heavily dressed with plenty of tying material or as a skinny version where hardly any material is used. Its best having a variety of dressed flies in your fly box.
