Howdy, all. My Tuuks gave up the ghost and I am intrigued by Sprung. Althoma1 refers to a newer, stronger version of Sprung... is that the Sprung13? Where is that model sold? At the Sprung website, I only see the A6, A7 and A8 listed. On that site, I also don't see any sizing suggestions. I wear a size 9 Mission boot, am just under 6 feet and weigh about 160 pounds. Would this put me on an A7 (medium) Sprung chassis? Does the Sprung13 come in different sizes? I play outdoors, on a concrete rink that's maybe two-thirds the size of a full rink. Would you figure 76-size wheels, with an 80 durometer? Thanks to this forum, I also checked out the Marsblade site. Those folks use the term "training skate" about a millon times, making me wonder if that means the chassis is not engineered for the wear and tear of roller hockey games?
