New route did in ratho quarry.
"Shoskred" in blue and it's central variation in doted blue, "Between Contracts" in red and "Cracking-up" in green.

Check lowland outcrops! Cracking up starts further to the right nearer the bottom of quick pull. Will have to climb between contracts next time as enjoyed shoskred.

Yeh this is a nicer variation I've always done, its avoids the mining scramble described in lowlands. Enjoy contracts, would say its probably the niceness of the three. I could be biased tho :P
