You may have already left!
I hope to these both this summer as well!
I started a thread a week or so ago in regard to the Pyrenean Traverse that has generated some useful info, IMO. There is a post there by another member who also has Type 1 DM, I think. http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=77858
Look forward to watching this thread.
PS. As for the gear, I will also take CAMP Corsa 60cm and Katoohla Microspikes...depending on reports. I would like to do some of the classic peaks and for these I think there is a good possibility that slightly sturdier footwear and appropriate strap on crampons might be preferable. I would like to find a way to have the gear when I need it and not carry it when I don't...without just giving away too much stuff! Those are my initial feelings. Anyway, I don't think it is worth getting all excited about specific gear. There are options and no, I don't think using an alternative routing here and there will detract from the spirit of the traverse! HRP is a "concept" not a strict routing...isn't that what Joosten says?
