I have a lucasi with the z2, it feels great, alot better then the standard shaft it came with. I have a uniloc joint as well with metal joints though, and i really favor wood. It is a soild feel all the way threw the stroke. It did take me a while to learn how the z2 plays though. It is alot different then a regular shaft. I got pretty flusterated at times. But once you spend the time on it, and learn it you will love it. I know i do!
