In reply to Marek:

If the Foundry wasn't quite *all* top rope back then, it certainly mostly was. Re-clipping on the way back down was often a bit of a challenge. All perfectly normal in the UK a mere 20 (oh God, make that 25) years ago.
Leading really does make a lot more sense on the steeper bits doesn't it, seems obvious now. (At least beyond the first couple of clips, bearing in mind in the Foundry's case this was also before rubber-crumb flooring took away some of the ankle-snapping hardness of the concrete beneath.)
