Don't just turn up at Coniston with your kit unless you have someone with you who knows the route or you will get lost, it is bolted but there are no ropes, so if your going to do it, it is best as a pull through. You need a 200m rope as I think the first pitch is 90m.
You went a different way to me then Steve! 90m? Not sure where that is.
The pitches we did are 6m, 29m (down to the top level horizon), 23m (down to middle level) and 25m (down to Hospital level). If you don't know hospital level, it's worth going in there first and famaliarising yourself with that bit.
There are surveys on here (search Coniston) and it's certainly do-able from them if your reasonably confident. Best way would be to rig it properly, find your way through, go back up and repeat the trip, pulling the ropes through - it's a pretty quick trip if you don't get lost!
