I'm an 86kg intermediate and have an XTS, Six and an NK Storm (not the Squall). All are great boats with differing applications for me.
Storm is my go to boat most of the time. It's probably similar in speed/stability to your EVO 3. I use it in harbour and light downwind conditions.
Six is used in medium downwind conditions. Added a DK rudder for more control.
XTS is least used, but I pull it out when it's really big conditions since it has the most stability. Definitely need the DK rudder with it to prevent broaching.
The Six is speedier than the XTS, but the XTS has more stability.
Might be worth your considering a V9 as well.
