If you are new to skateboarding and are looking to build a custom skateboard complete, the best place to start is with the deck. While not all boards are created equal, groms will do well on just about any brand skateboard offered at CCS as durability really won’t come into play until riders start to skate bigger gaps and transition. So your focus should primarily be on finding the right deck width, board graphic, and brand that resonates with you or the rider.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
