Some of us have had HS225mg servos fail. Search on RC Universe and you will find the details. I no longer use them.
What size plane are you flying? I have had good performance with standard sized servos from Futaba, Hitec and Tower Hobbies.
Among the pushrod options you might look at Dave Brown's glass-epoxy arrow shaft pushrods. I also like 2-56 piano wire in a sleeve.
Locating your servos in the tail with short wire pushrods is a good option for a 3D funfly.
