Thanks @Glydon. Sounds like we are narrowing down what it is. Do you recall if this ski had a specific model name? Maybe it's just a "sonic" and it's a pre c6 version? Guess I could be in worse company than Jamie's junior ski .
Guessing the posted C6 specs would not apply to this ski....?
When I get a chance, I will still post some more detailed pics of the hull per Drago's request.
