its a nice board with a constisant pop. Im not really good enough to notice the difference between swing weights on boards but i really dont notice anything when i am spinning so theres that. It seems with edging you have to edge a little harder to get the width of the board to carve into the water to try and get maximum pop but otherwise yeah the turns are pretty quick on it considering its got 8 fins. The board also lands incredibly soft in the flats because it has a massive spine in the middle of the board so if you looking for a board to land in the flats with you might want to consider this one.
i got the fish about a year ago and i love it. im 6'0 165 and ride the 129. if you want to spin really fast then you could probably go with a 125 but that seems kindof small but the board is awsome such soft landings and can turn fast with the 5 fins.
