Futaba steering servo choice
Hi all, I am :frusty: on choosing a good Futaba servo for my S-BUS2 install in my new pursuit hull. I have narrowed it down to 2 choices but I am not sure which one is best for the boat and racing. My main goal is not loose control or have any kind of servo stall when turning at high speeds.

I am leaning toward BLS471SV because it has the speed, but the BLS371SV has more torque, what would be best on water during racing conditions?
Thanks,
