I think it’s about travel, the monoblock is great but travelling is painful.
I only have the Enduro 1300 of the range and it’s the best big foil I’ve ridden. Certainly the system is very stiff. It relies on tension in the screws, so get a T45 and keep it tight.
The Silk 850 is probably the happiest I’ve been for turns, I want a 650 and a smaller version too. It is crazy smooth. To come back to the surfboard analogy, the Silk is the closest thing to a high performance shortboard. It is not easy to pump.
Will get a go on the Code S foils to compare, but a friend tried one from Axis and it looks amazing, really unlocked their turns. looks much more of an all rounder, where the Silk is so obviously built to push turns, and super forgiving to hit the foam.
I don’t think this is the right way of looking at it - for each, add the cost of at least 2 foils and 2 tails to get the “true” cost. The difference I think went away or was lost to specifics of combinations.
