Getting on and getting off the Candlestick is quite a bit more involved than the Totem Pole. I wrote down some notes but I can't find them. Hopefully someone else can help you out. The Tyrolean to get off the Candlestick (having already done one abseil from the summit to a good ledge with fixed anchors) is situated much higher on the Candlestick side than the mainland side, so you need to consider that. The overall length of the Tyrolean is a bit more than 30m as I recall.
