I usually ride it with my Katanas so I could set it back more but the ‘float issue’ with the EA is not the tail to nose surface ratio, that is already very much float-oriented. It’s the full high camber bend reaching the contact points and a short upkick section in the nose. If they wanted to give it more float, they’d need to put some 1-2 cm rocker there and add some length to the nose upkick part.If you fitted Re-Flex to it rather than EST you'd be able to get a lot more setback on the front foot (and consequently to the rear) which would assist it better in powder.
I’ve been riding the EA with +27/+6. Works great on groomers. But for jumping (where it definitely shines) I prefer +24/-3.
