If that's what you got then yes, it would be better then stock. But get one to run the whole length. The longer it is the more it will protect from breakage.
I have a few EasyStars and have broken the outer part of the wing where the spar ends a couple times doing something I shouldn't have. Most stress is towards the fuse but the outer tips take a beating too.
