What size fins are people using on their Hypersonics for a given sail size?
I'm thinking of get a smaller fin <40cm for when the wind kicks in and I'm using my 5.8m sail. With the 40cm fin the board has a mind of its own (more than usual) and is difficult to get to sail down wind.

The Hypersonic comes with 2 fins, well they should. You get a 44cm and a 34cm. I use the 44 with an 8.5 and a 34 prolimit (the orig 34 I snapped, there was a recall on the initial 34 cm 105 fins) with my 5.8m. Could probably even go smaller, say 29 with the 5.8. You definitely want something other than the 44 with a sail as small as a 5.8, the board just feels too 'draggy' with such a large fin and small sail.

I had a 105 hypervomit about 2 years ago. Used 44 cm with 8.5 (also) and 36 cm with 7.0. My 36 cm pointy slalom thing. Sails more like a 34 cm. Thought those sizes were about right.

light 6.7 38cm
moderate 6.7 34cm
strong 6.7 30cm
moderate 5.5 34cm
strong 5.5 30cm
haven't used smaller than that- it is really taking the hyper out of it's comfort zone. If I was to get a range of fins for the hyper minimum would be 30, 36, 42 and 48 to cover 5.5-9.5.
