Had a chance today to try my friends Lf Impulse on the new 2019 galaxy 4-6 board.
I'm riding a 120cm custom pocket with 2016 93cm fluente mast and 2018 Moses Onda 633.
I was quite surprised. The Impulse is hugely more pitch stable, but also yaw and roll. It turns pretty good but needs more input. Some of it could be the board. I felt like I could have taken a nap on it while flying.
The Onda is in another category it's so different. My friend was blown away by how quick and loose it was compared to The Impulse. My impression is that the Impulse would be a great learner foil, but I'd get bored with it really fast.
