Upgrade from E74 2003?

[think]

OK, it's time to separate from my trusty E74 first model 2003??
So what shall I choose??
Weight: 81Kg
Sail range: 3.7-5.3m
Waves: 1m to mast+, side to cross on
Most common condition: 4.2m-4.7m 30knots head waves cross onshore
I also got a AB+ 87l as a light wind board using 4.7m-5.3m.

I want a looser and faster turning board specially on the top turn.
I'm thinking about 1 maybe two board quiver.. considering the Evil twin 80 as one board??

Any advise?
