Still have a 105 in the shed, was the first board I used with a foil acually I never sold it because at the time is was such an out of the box design and worked really well I thought...maybe there is life in the old girl yet. I don't think we have quite such accurate pitch control though
If your foil has the front wing placed very far forward, like RRD, it might work fine. For Naish WS, might need another 4" via P Plate to get front wing COE between footstraps.
Local master foiler here (Bob) has been using a Hypersonic since day one (4+ years of foiling) Its the most Frankenstein board I have ever seen, so many battle scars etc! but he is still foiling it every week with the Slingshot HG foil (TC 68 and I84).
These low aspect-ratio shovel-shaped wings seem to have a very broad center of lift. I use a i76 in B position on an old formula board with the finbox in the stock position way far aft. It balances just fine and works well.

Nice one! Style points for having the life jacket straped to the inside of the harness
