Aipa Big Boy Sting

So I'm thinking about getting an Aipa big boy sting. It seems like it will fit in the space I need for days that the waves are smaller and or softer, days that I'm feeling my age (53 now) or just want to suck up all the waves getting in early. A funboard on steroids is what it looks like and at my current 105kg seems like it was aimed at guys like me.
What I've read here and other places is that this is a special board. If anyone has any experiences on it please share; I'm still on the fence but want to be sold!
Also, what size should I get? Size range now is from 7' 59L to 7'4", 7'8", 8' and 8'4". My first thought was the 7' but maybe this board goes better in bigger sizes? If anyone has any insight on this it would be appreciated.
