I read a lot about the 520vx hull being some of the best ever built. Just wondering why everyone thinks that? I currently own an 05 520vx that I've had for eight years. My regular partner has a 2016 520c that blows away just about any and everything about my rig, in my opinion. Space, storage, and ride for sure. Thinking of selling mine this fall to buy an 520c or L but have second thoughts everytime I hear good things about the older boats. Just wondering so please give me your opinions. Thanks!
