I had a Goode for 8 years and could not get past 3 ball on 12m. Swapped it to the D3 for one season - no improvement - nothing wrong with it. But the D3 Quest was a very dull ski.
I tested the Radar & was sold just after two sets. It was just fun to be on, it reacted to what you put in & quite quick low effort skiing.
My conclusion is its the best ski I have ever had in 33 years of skiing (all the way back to Connelly HP days). Turns evenly (that for a start is impressive out of the box) there is lots of info on how to set it up. See Horton's review + the official Rini/Rossi settings. I'm a pass up in two seasons so a very,very happy skier. And its without doubt the ski has helped me to run12m .
A friend this week has been testing the Goode flex tail v the Radar 2015 model and he is preferring the Radar. His comment - even turns, fast across the wakes but makes a nice predictable turn, & as its not as stiff as the Goode it more forgiving.
In the UK you do see the Green & Pink 2014 models everywhere at every level which is odd as it says it is a top end ski. People just love it I cant see the same response to the D3 here in UK
Pro skiers ski on specials, tuned skis, stiff skis/soft skis, the best of a batch of 25 they tested. Skis glued together & they have talent.
My advice is take a test and see what feels good then go from there!
Or just buy the Radar
Good luck
