There's a huge debate on not using gyro sense for smaller aircraft. That it was originally intended for larger aircraft and especially for governor mode.

Since I have flown both and can see no difference I say setup for whatever is easiest for you. True I only gave gyro sense a month try before switching over to gear endpoints off the gear switch so I can't offer any support with gyro sense.
Vibrations are hard to track. Low head speed can cause it, something is bent, something is out of balance, something got loctite in it and is sticking, ball links too tight. Check everything...
