I'm sure this is going to have lots of opinions . It is time to upgrade from my 2005 Avalanche. I am leaning to a newer RI237. Centurion did a hull design change/upgrade? in 2018 so not sure if I should be looking for a 2018 or newer or if a 2016/2017 would be fine? Not sure if I should be concentrating on the RI or look for other models as well, all we do now is surf , the body can't handle wakeboarding anymore . Any and all input will be very much appreciated. Thanks in advance
