As the name suggests, this is a cross between hollow and a solid elastic, it has all the benefits of both without any of the disadvantages of either, it has maximum stretch just like a hollow, a lower diameter and a smooth surface just like a solid, and it doesn’t suffer from flattening which sometimes can be a problem with  hollow, especially in the cold months making this the perfect ALL SEASON pole elastic. But most of all due to its structure it has durability and superior strength which makes it perfect to withstand the rigours of puller kit fishing.  * Designed to withstand the extra friction of puller kits, while retaining the 700% stretch factor of standard hollow elastic.  * Perfect for silvers to F1\'s to big carp.  * Extra Strength.  * Perfect for puller kits.  * Available in 7 sizes ranging from 4-6 to 16-18  * 3m Lengths
