Man its been a while since Ive been around all the new options for archery. I do know you can go over board on anything. Ive seen bows that had so much extra rubber silencers on them that they felt more like a boat anchor than a bow. 2 string silencers and 2 limb savers is fine. I don't know what the ultra jax 2 looks like.
Runnin'em down like a dog has always worked best for me.
