I need new Skate wheels for my deck?

I want to get softer wheels for my deck.

I need wheels simply for cruising only, no tricks at all.

whats a good size? is 60mm good?

also what softness?

what does the expression "97a" tell me?I need new Skate wheels for my deck?
i agree with the other guyI need new Skate wheels for my deck?
i don't know what 97a is but i would buy darkstar wheels they are very smooth.
