Well, its really an offtopic, with a sence of supernatural

Have you ever had the feeling, that with time your blade has changed its character to match your soul?

Why do I ask - me and my son are playing with same setups for more than an year. I've chose them to be exactly the same and they felt the same for more than an year. We used to exchange bats with no sence of difference. But the last month my boy told me that he feels my blade different. I took his and I felt it different too. And the bats played differently exchanged. Other players didn't find any differences, but we do.

So - do you believe that your favourite gadgets may get a synergy so deep to change the way that fit you?
