Hi Zak,
first thanks for the trust in the Fanatic boards you already have!
So, have you ever foiled before? It sounds like not, so will assume so - I would say go for the StingRay 125 in either HRS or LTD - Flow Foil (you need the mast and fuselage too) 1500 - and then you can get a 1000 Flow front wing later if the 1500 feels too big.
The Falcon Foil is good for racing, the Falcon Light wind is also a very good light wind/Slalom fin /foil board, but since your biggest sail is a 7.8, I don't think the right fit - you are pretty light and when you use a Stingray you get the max advantage of being able to use a smaller sail than normal.
