For those of you new to powerbocking, this is a handy chart for you to easily determine the proper model for you. There are three main companies making bocks catered to non professionals. Poweriser(Korea), PoweriZer(China), and 7LeagueBoots(Austria). PoweriZer is just one brand name that the company distributes their product as, they are also known as Fly Jumper, Pro Jump, and Flying Locusts.

The chart below has all the models I know of that are currently being sold, excluding professional stilts, PowerSkips and Velocity Stilts.

Listed is the manufacturer, model number, advertised weight limits, and what I think are more realistic weight limits if you want to get the most out of your powerbocks. You'll notice they are the same for 7Leagues and not for the others. 7Leagues seem to be the only brand that has correctly set their weight ranges, but if you intend to go to the extreme on your bocks moving a step up may be the way to go unless your at the very bottom of the weight range. PoweriZer represents Fly Jumper, ProJump, Flying Locuts as well as itself in this chart.

This list may not be final, but it is accurate to the best of my knowledge and I will update it with any changes as they are reported to me. I intentionally left out PowerSkips and Velocity Stilts because they are out of the price range of the majority of the users here. If you really want the sizing info on them its available here. Velocities use Powerskip springs so the selection is the same for them. I don't know how accurate the weight ranges are for everyday use, but for extreme use they are still a little high, ie swebounce and hemoves use 640's but i think they're both below 70kg, but not by much.
