Hi,
I am the same weight as you and has been using an 88l freestyle board as my biggest. I then have smaller waveboards for hen it's windy, like 66l.
I have learnt a lot of new stuff on freestyle boards, they are quick to plane, have a good windrange and can even be ok in small waves.
My starboard flare 2009 88L is for sale, 400gpb. Email me if your interested
