Still voted No'1 Elastic in Europe, Middy Tackle's original Hi Viz solid elastic takes some beating. Used by may of the country's best anglers due to it having much more stretch than most other pole elastics which results in less bumped fish.

Starting from 3 to 4 elastic (green) which is perfect for fishing down below 1.7lb hook links, Ideal for canals. 
Through to 18 to 20 elastic (blue) for those big fish hauls on 8lb main to 6.1lb hook links.
