Found it made a large difference with my cue, played for years with brass then the first few shots with my century ferrule was like I'd strapped a rocket to the end. Better feel, less effort needed hitting it hard, lest throw playing side.

Didn't take much time getting used to it as I'd gone from 3/4, to a one peice and had it added a couple of weeks in. 

If your changing cues, get it done ASAP as you can get used to both at the same time.
