I've been to Lanzarote and from what I know it has big swell (costa teguise).My suggestion is that you should take the Evo I think it has a little more variety, if there are waves you can have some great fun wavesailing.
Also if you want to freestyle the Evo will do fine. To me the flare is a pure freestyle board. I think Noah would do great on a Evo...
But maybe you should wait and see about what other people think
