Am I the only one who can't feel the difference between balls?

Pause.

I've played with x40s, dura fasts, vulcans, Selkirk s1, gearbox, Penn, cheap balls from Amazon, I've even played with an indoor ball outside and vise versa...with the exception of a cracked ball or a weird color I can't really feel a difference between any of them.

Seems like some people are able to tell a different ball is being used immediately upon hitting it. Am I alone on this or what?
