well my risers arrived on Saterday, had a coupla goes and got pretty sore. takes a while to build up those back muscles. I got the heavy springs, 90+ and I'm only 70kgs so its going to take a while to wear them in and they jar a bit. at least they wont break for a while. Got some good hight. tried a few spinning kicks. Jumped off a trampoline. I was all revved up before I got em thinking I'll just get straight into some back flip but when I put them on and remembered the weight and all I got butterfly guts. I'm going to drill through the foot plate and attach shoes. The snowboard straps are cool but even a little movement in the foot and it throws the balance off. Circus stuff were pretty swift and nice people and their websites well organized, check em out if your into fire, juggling, unicyle etc. My powerisers 07s cost $549.45 plus $25 delivery.
Look forward to the next meet you guys.
