Depends...
If you are going to use the original shafts...definately Lambros, they hit absolutely amazing.
If you were to decide later that you wanted to use a predator or other LD shaft, stay away from the la,bros, it's why I sold mine, can't get a pred shaft for it, would have to be custom made, and his LD shaft I didn't care for.
Great hitting cue tho, I'm just an old dog and like my predator shafts. I've found that for me, cues wih funky joints just get in the way of my plans, no matter how well they play.
To each their own.
