Hi Fatben,
as asked here's some pics of my 9'0x32 Mongrel shape Indo Travel / Share board , it's Not a 4 in 1 , NO - Windsurf or Foil fittings.
It's been a fun board , done all I've wanted and more, traveled well, liked by all that try it . A delightful Mongrel of many personalitys.
It has more nose concave, turns well from the middle, agile tail.
Originally setup as Split Twin and center box, later added parallel to centerline boxes for BIG Twins.

Ben ,we are similar in build, not your average Pixie

Istri showing off the bottom contours

Original fin setup

Added parallel to centerline Big Twin box's

Giving the Bonza fins a Indo thrash cause they didn't get a Darwin bash

so Ben , at your weight n height on a 9'7x32 @156lt on the Todd River, Alice Springs, Centre on Australia . The Funky Mongrel has sighty less volume than this. Hope this helps with your search for THEE next board.
Enjoy
