I fully agree, 3 days will not do justice to paynes ford. And also, dont know how much instructing will get done down there, think its just going to end up a climbing trip... 

However I am contemplating running a trad climbing trip to mangatepopo, possibly tying it in with snowcaving if i get 3-4 keen people who are ready to move on from sport climbing.

also had vague thoughts about mountaineering around arthurs pass during the break...
