Ok, I will state my personal, non-Alkali opinions of these. This entire post is my own personal opinion: Does Sprung work - For some people. I personally do not like them at all. I do not like how the front wheel compresses, and feel much slower in them, have a loss in balance, and overall I am not comfortable in them. Do they turn better -Maybe. Personally I like how the back wheel compresses (this is funny, since I love how the old Vibe 2 chassis compressed in the back). Is there a place for them: Sure, some ice guys would like them, but I feel they are more of an off ice training tool. My opinion is you should support brands that support inline/roller hockey: Alkali, Bauer/Mission, Tour, Labeda, Rink Rat, and Revision.
