Bought my 08 Avy New in 2010. Wave is still awesome. I have 9 years of playing with my wave, every year I try something else to improve the wave and it usually does. My buddy just purchased a 2016 SV233 (ram, cats and quicksurf tabs). His wave is good and we are still trying to find the perfect setup for his boat, but I think my wave is taller, longer and more push. Again mine has been tinkered with for 9 years and his just a hand full of times out. Listed wave is much better than the tab wave on his and mine is always listed.
If you need to swap back and forth quickly, get a new Centurion (Ri, Fi or Vi). If your family all rides goofy or regular then get an older boat, list it and run it and save a bunch of cash.
