The best skateboard is whats best for you. I like a lot of concave and a whole lotta pop. Another major factor is the wood used in the deck. I recommend anything from Kayo Corp. (Rasa Libre, DGK, Organica, REAL, Crooked, Anti Hero). Each board has its own shape and personality. I got a board to ride in the rain, one for parks, one for daily street, and one for drunk cruises late night. Id stay away from Birdhouse, Hook Ups, Alien Workshop, Element, or any other major, mass distributed MALL SHOP brand decks… THey have horrible wood and tend to snap like twigs.
Dont worry about how heavy your board is. Make sure you got good wood, good bearings for the wheels, and some good griptape (Blackmagic, etc..). The trucks should be sturdy (I ride Thunder or Independent——tend to be heavier style trucks) but Ventures or GrindKings are fine too…
