How do they help or do anything special that normal stumps wouldnt ?
Here is some more information......
The stump's are nearly unbreakable,very flexible, the ball goes through the stump, very safe, good for keeping practice,can get very close to them when bowling,,,don't hurt your hand if you hit the stump,
Extremely light weight, can be detached easily, can put short stumps on,we have a flat base for indoor and out with various hole patterns, we various Yorker targets ,these have all got common threads.
And don't forget it has got the Patented safety spike cover a loop to help pull it out of the ground,if you add up all its points, it is a Multi stump.
Fusion came up with this idea, having been ask by Eng coaches for Harminson,he was braking so many stumps in practice, and the keepers were getting impaled.
