I was having a gander at the GA part of Coffs Airport yesterday with my boys (1 and 3 years old, so they love planes!), and had to stop and drool over a PC-12 on the GA apron. The pilot taxied to the short runway (one-zero, 849m), backed up as far as he could, held the brakes on for as long as he could, and then took what seemed to be the whole runway to get airborne. The wind was not strong.
Coffs has a 2000m long, 45m wide grooved main runway. Why would you take a chance on the short runway when the long one is available? Any thoughts on why you would make such a decision? It's only an extra 1 min taxi, and there was very little traffic, being a Sunday afternoon.
