Hi Martin, we did a bit of testing with the SL- fins on those, not too much with the SLM - but with the flatter rocker these boards have, I think you need a more powerful type of fin, which for me is the SL-?
94 - 33/34
108 - 36/37
On the 94 you could probably also get away with the SLM if you sail very powered up, as you are fairly heavy/tall? same sizes?
