Rotten Bananas 

This was a retrobolted old route, FA unknown, you can still see some old bolt holes. Also, the route length is 105', you can't quite get to the ground with a 60m rope, but you can get to the ledge shortly off the ground.

craig service and myself hand drilled a 4 bolt 5.8 up this wall in 89': called it wadcutter, the base was really shot up
on the back of this formation is a three bolt arete to face we never completed

I can confirm that is more than 30m to the chains. Greg's 105' seems right.

I thought Rotten Banana's was slightly more difficult than Bananarama.

I agree with the beta on the rope length. We had a 60m and it was a rope stretcher. My belayer stood on the hump/ledge to meet me. The 70m would have made it no problem.

This does have a thinnish move about 3/4 of the way up that's "harder" than anything on Bananarama.

Also note that it shares the last bolt with Bananarama (and yes, your belayer should tie in if you're on a 60m)
