Futaba steering servo choice

[Impulse31]

Hi all, I am 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,

Are you dead set on futaba?

I will be using the SBUS-2 for sensors and their servos seamed a logical choice minimize wiring. Are there issues with Futaba BLSxxxSV servos?
