Amplitudes, especially in the 5 to 6 foot range can be possible on most but the ballistic impact reducing ratio is the primary concern for most people. Most people don't understand this until they do it. Depending on your weight and how positional tolerant your legs are, this can be a concern.
Different stilts give different amplitudes with different energy expenditures. Some give more free bounces than the other with minimal exertion and others require more muscular strength to get to the higher amplitudes with more previous bounces to get to that level. I always take into consideration the ballistic impact at the higher amplitudes of 5 to 6 feet. Some jolt you more at the bottom and some are more of a "rolling" uniform deceleration. It is not just about finding a stilt that gives the highest amplitude from a super responsive spring without understanding G forces and ballistic impact. I have studied this field with stilts, not just how to do tricks and all about fun. My stilt quiz is also set up to pinpoint the stilt that is best based on someone's answers. I have bought nearly all the brands and tested them with different people in different weight classes so you don't have to. That is why the people that want this particular help in this niche contact me. As I think about it, it reminds me of Foot Solutions where you are in there for about 45 minutes and they put you on that machine that films your walking or running pattern and they have you stand on this thing that shows where most of your weight when you stand and they squat down and watch your feet as you run down the sidewalk to see if your feet invert or whatever they do. So, think of my quiz like something of that nature.
As their are different brands that have different types of springs and frame formations, I had to take the different pairs to several engineers to help me understand how I read someone's quiz to balance the ballistic impact in order to get a stilt that will get to the amplitudes people want. If someone has bad knees or they have inner ear problems that cause them to get dizzy, such as when doing flips in the air which give them the same problems as those that get dizzy on a roller coaster after just one ride.
Some people want a workout and some want to expend the least amount of energy when doing stunts so they can do it longer. Some people might need to get their stilts charged while others can use them right out of the box. But, most people don't want to wait two to three weeks to have their stilts charged. I am actually wondering if some of the people who do the craziest stunts you see in some of the Youtube videos haven't charged theirs also. I doubt any of the manufacturers are using charged stilts because it would give a fake impression because if people bought their stilts and they couldn't do what the people in the video did, they would be returning them. I am not saying you should get them charged, it is just an observation.
About gaining higher amplitude, whatever the case, when 80% to 90% of the ballistic impact is removed from the bottom of the bounce, people usually don't complain. On my quiz, someone's weight plays a major difference. At 4 G's, if someone is 160 pounds, it is really like 640 pounds exerted. Wearing something that weights 3 pounds is also like having 12 extra pounds of force which can also affect amplitudes. It can make the difference between bouncing to the 7th step or to the 8th step on stairs.
My quiz will help pinpoint the right pair of jump stilts based on your answers. I will only recommend based on the answers you choose. I have access to all of the major brands that I like and not pushing just one brand like stores that bash other brands that are not the brand they sell. Each stilt can give the same amplitude but remember with different energy exertions and ballistic impacts which can be right at the end or near the end of the bounce. Depending on your style I will help you pick out one. Take my quiz here.
...Because I had to buy 3 pairs until one fit.
