I use a 425pro Weapon paddle after using some other brands that felt awesome but ...
Thanks all for your feedback so far.
Crazybula, looks on the picture like the 425 paddle blade does not have any profile (dihedral, power pocket, etc). Is that correct and doesn't that make the paddle exhausting to paddle long distance (20+ km or miles).

This is the blade contour from the 2019 model. Only just come across my desk and I'm stinging to get home and assemble it!

Thanks. How does it paddle? How about flutter?
Like all high-end paddles it paddles well and there is no flutter.
