I don't know what the top 5 best decks are. But here are my current favorites:
1.Flatface G12/13 - Both versions are great! All three decks that I've owned perform great, and look absolutely stunning. To be honest, if I wasn't out of RipTape, I'd probably be riding one!
2. Berlinwood 2011 Low/Flat Shape - A fantastic shape that lives up to the hype in my opinion. There is kind of a weird discrepancy in all of Berlinwood decks btw. There are some decks that are slightly thinner. I know Elias Assmuth personally picks out the thin decks to use.
3. Berlinwood 2009 Regular Shape - The deck in my Dynamic Symmetry video was the best performing deck I've ever used! However, the other decks from 2009 I enjoyed, but they weren't nearly as amazing as that deck.
Honorable Mention: Prete Metal Heart Custom Shape - This is my favorite deck I've ever had. Completely one-of-a-kind shape! It is extremely thin and light, and had amazing pop. Unfortunately, it was really difficult to land tricks clean, since it's soooo thin!
As you can tell, I haven't had much experience with other brands of decks!
