Hi guys,
Just to weigh in with 2cent's - awesome idea to produce a definitive topo to the wall Neil - it would make an unreal wall poster a la the Yosemite Super topo. Pretty much agree with all the commments above, including Father O worth 3 stars (can't believe I'm saying that on a public forum). Only addition I'd make is that there is no way Feather Boa is 28 - it took me four full days complete with a last move bungle and having to come back for another redpoint. Its at least a full grade harder and quite commiting, but the grade is difficult to define as the cruxes are by no means straight forward. Regardless it's the best route I've done on the wall and one I'll remember forever. The last pitch is really cute too.
By way of comparison, around that time I did a bunch of other routes supposedly as hard or harder on the wall 2/3rd try - so to give FB 28 you'd have to give venom 25/26, and groovy, Cardigan St & anaconda - 26 too. Whilst on the topic of Anaconda it's worth mentioning that doing all three pitches in a single pitch on a 70m is highly recommended. In fact it's possible to do World party as a single pitch as well - great fun.
Mr J also deserves 3 stars at least - has to be the best 25 in Australia.
