The Orangatang In-Heat is a phenomenal wheel for high grip applications. This wheel is perfect for your Loaded board, or for a board that you want high roll speed and grip. The 80a orange has a ton of grip at first, but if you break the skin it will slide super smooth on DH runs, and was the race wheel of choice for many years. The purple 83a is quite a bit more durable than the orange and offers nearly as much grip, but with a more chalky wear to it that you can rely on to last longer.
