The XXX is stronger, and not as smooth. I've been trying to replace mine for a while now. My boss at the shop says the Hot Rod Hybrid has the same reaction shape to it. I had a Recharge, and that acts a lot like the X did too. I'm drilling a Fired Up here pretty soon, so I'll see what that does and let you know.
