One of the appeals of the Wilton niters was they always had, along side bigger name DJ's, lesser known's too. They might have been well known in the collecting circles but to the dancers relatively unknown as DJ's. As collectors and having an "ear" for a sound they often had a knack of playing records you would have thought, on paper, totally unplayable side by side but spun to great effect.
You need a balance if running a major night. Local soul nights folk will come along regardless, few pints, few dancers and home happy. At niters and major events you do need the names but you also need to give lesser known DJs a chance too IMO. Most of all you need DJ's who can work the floor, known or not...not some wanna be who just throws records on here and there, like Mike said it's got to flow, they have to get the balance between the tempos and styles right.
