Most Important Part Of A Setup?

What do you think makes the biggest difference performance-wise in a setup?

I think grip makes a massive difference, but also the deck and wheels make a huge difference too
what do you think?

I'm not gunna vote, cause I think everything is important... u can't fingerboard with out the deck... cant fingerboard with out wheels, cant really fingerboard with out tape... cant fingerboard without trucks... yeahh....

i mean what makes the most difference from a tech deck to a proper fingerboard setup

Oh well the deck of course
