In reply to matthew2ts:
Can't help with the guide I'm afraid. But are you going to acclimatise at all? I did the breithorn half traverse having had one day acclimatisation walk straight up and down to 3000m, but found I really suffered on the traverse as you spend quite a lot of time close to 4000m, rather than just a quick up to that height and immediate descent.
Your experience may be different.
Great route though, hope you get it done. The half traverse is very straight forward, it was my first real alpine route.
