Cray,
Im learning (again) on a 130lt JP Xcite ride with a 6.6 and 7.4 Loft o2 freeride sails. These give me plenty of range depending on the wind.
I weigh about 90 kgs too and the 130 is big enough to uphaul on or drown next to when trying to waterstart.
I highly recommend this board as it is easy enough to learn on (sort of) but will definitely not be outgrown in a hurry and will become a excellent lighter day board as I progress.
