All carbon foil including fuselage, especially if you are in saltwater, that reduces your choices by a lot, but eliminates equipment failures. AFS sells from their website a foil with an 85 cm mast and freeride wings, the F1080 cm2 wing is great in light wind (I am 82 kg too). It is actually a bargin, and bomb proof, just remember 20% VAT comes off the price once you select an out of EU address. I got it because I like to go fast, but not as easy to learn to do a foiling gybe like bigger wings, but they are slower and take more effort to get up in light winds. I put the AFS W95 (no longer made but essentially the current 85 cm foil with a 10 cm longer mast) on a Goya Bolt 135 slalom board with a foil box, still happy with it +2 yrs later. Just beware of slalom boards with broad recessed concave decks like my 2019 Bolt, mast can dent them up on the concave deck ridge, but for the Bolt a 3/4" sail mast base spacer solved the problem by raising mast base high enough that mast hits board on a flattish section of deck.
Foils are quite a bit slower than windsurfing, but can get up in lighter winds with smaller sails, and then big wings are slowest, so just make sure if you start with a big slow wing you have options for smaller wings once you get bored going slow

And as mentioned, try before you buy, if possible. AFS has a 14 day satisfaction guaranteed or return for full refund policy and 3 year warranty, do not know of any other foil with either a return policy or a warranty as long as 3 years.
