Well done rancher, my kids saw that and got on the tram trying to copy you and didn't get very far
Does the brand not have something to do with that?
I read that those ones allow you to bounce higher.
I've found the following from my experience to get max height:
1.
You have to get the technique right first off: if you are not very good won't matter what brand you are wearing, I've tried a few different brands and wasn't getting any way on any of them when I first started bocking.
2.
Stiffer or newer the springs, the more you will get out of them: I upgraded my old PJ springs for the black ones of the same size and was instantly getting a much better height, I've not pushed them as much as I did my old ones they are still stiff but I feel I can get a lot more out of them still.
3. Some say that the Powerskips give you a better return with little effort, same has been said about the new Projumps black spring and also the higher weight cat 7's Srex so its hard to determine the brand statements as it would be extremely hard to proof one way or another.
