The primary issue is your basic ride. Take a look at what you feel comfortable skating and work from there. Fact of the matter is, you can slide any deck and any setup but your deck should allow you a comfortable, shoulder-width stance. With the variety of longboard-style slide decks out there, it should be easy to find something that not only conforms to your height but agrees with you as a ride.
For real manipulation of your board in slides, you’ll want a deck with some concave, good pockets, and comfortably accessible nose and tail kicks. This will help to lock you in with rotations and pressure the deck during slides. At 5’10”, the Earthwing 35.5” fits my body size just fine. Earthwing, Gravity and a number of other companies make decks in a variety of sizes and concave styles, so you should be able to find something that fits you. Like Michael Bream once said, “The most important factor of a slide deck is that you feel comfortable on it”. This is too true: to pull multiple rotations one need not only to be able to get up to speed but to maintain control, once you slide.
