How long to get used to new irons?

There some interesting comments about feeling right here - why would you both to have a club fitting if you are going to pick the ones that feel 'nicest'?

Surely you? get fitted for performance, and over time you will become used to how the club's feel?
 
Won the monthly medal with my new clubs on second outing with them, saying that, went from S55's to rouge x, so a lot easier to hit for me.
