The latest Energy X-tra is pretty amazing. It already has a built in glue effect, and from my testings, lasts a very long time. It's been over a month, and you still hear that crazy corked sound! It has a very nice soft sponge (which I enjoy) and gives you great feeling when you loop or hit. It has a high throw angle, so it's definitely nice for off the table looping.

Mambo GP is a soft rubber too, but a little firmer then Energy X-tra. It also has the built in speed glue effect, and is still lasting over a month now. Mambo GP's throw angle is a lower angle, which is great for loop drives in my opinion, and good for hitting. So I prefer this on my backhand.

So if you enjoy softer rubbers, not having to glue each and every time, and still get amazing sound, speed, & spin, give these rubbers a try!
