If you go for the vini chat with philippe first, they are mostly advised for upto 95kg's, and warrenty doesn't apply for heavier riders! I really like my lok?, which is okay for riders upto 120kg's, if you're not jumping. The starboard would also be a good alternative I think. The pryde alu is really durable and tough, but doesn't offer a lot of lift (meaning you wont really be flying much earlier than 12 kts with a 9.5 or something with your weight. The AFS foils are also really stiff.
I find the pryde aluminium( blue) decent as a first foil. I pritty far from a heavy weight though (65kg) so can't really comment on durability in this case.
I decided to try and make a larger front wing 80cm in span with a chord length of 17.5! I'm thinking of making a larger rear wing aswell but am hesistent to since the aluminum gets so thin back there worried it may bend and I'm not sure it would help that much since I find I have a lot of back foot pressure already.
It is a shame brands are not really promoting big wings for heavy weights or just extra light wind in general.
If you have backfoot preassure, putting the washer in between the stab and the fuselage so the wing is angled downward more when its under your board will help shifting the preassure forward / increasing lift. The backwing doesn't push up, but it pulls down slightly, thats why its called a stabiliser. In the ideal situation (well designed foil and good match with the board / rider weight) the stabiliser gives a neutral preassure (or no preassure at all), because it is only meant to stabilise, which means inducing drag/lift when the foil is out of tilt and not doing anything when the foil is level.
Yes, I normally run with the one washer in the stabiliser so it is tilted down. I know the more angle you get tilted down the more stable and slower it will be, but....would a bigger stabiliser wing create more lift/ less back foot pressure?? Does the stab size not matter as much as the front wing for lift.

For the lift of the foil, the front wing is of way bigger importance. The stab is a nifty little thing to have aswell, but it doesnt change the characteristics of the foil as much. I think a bigger stab might slightly change the preassurepoint forward, but I have never tested this in practise. I have sailed with stabs with different profiles and layups, the changes it made to the characteristics of the foil were minimal, mostly increasing or decreasing pitch stability and a little upwind power. The best way to go about it would be shifting your front wing forward, or increasing the front wings surface to the front of the fuselage rather than the sides or back. It is also dependent on the board, the further back the straps and mastfoot, the further forward the preassurepoint would be. This is also a good point for heavyweights, since I have generally seen that heavyweights do better with the straps and masttrack a little further back than average. In boards you could think more in the range of the Jp Hydrofoil's specifications than the starboard boards, or for example the exocet RS81/91 or the Elix F1X. Most slalomboards and especially less radical boards than slalomboards have their straps set too far forward for use with most foils, with the prydes being at the extreme end of backfoot preassure, meaning they would have the most to gain in being combined with a dedicated board.
