What tail servo should I use

[WildWake]

What tail servo should I use?
I have a JR8900G,
is it worth putting it on my Trex600n,
it has an Align DS610 fitted at the mo...
Running 4.8volts,
The JR8900G 48.0 oz-in (3.5 kg-cm) of torque & speed of 0.05 sec/60°
The DS610 133.3 oz-in (9.6 kg-cm) of torque & speed of 0.10 sec/60°

610 is not a good tail servo-use the 8900 out of the 2 on the tail.
