Love the RRD wavecult quad. My 2012 is the best board I have ever ridden.
It is more onshore biased and earlier planing thatn the Hardcore quad so would tick the boxes for Scabs. In fact, I have no idea why they make a more rockered one as the Wavecult will do anything you want it to on a wave.
Lots of range too, at 95-98kg this summer I have used it from maxed on 4.5 to just planing on 5.8 - not a bad range for a 100L board

So the 83L (?) could be good for you but you may need a smaller fin set or maybe find it a bit uncomfortable in winter / Gero / Ganaraloo etc
So now I want aother one and I bet it was Leech who bought the 92L I had my eye on :(
