Anyone tried the new optional stay in the 2009 circuit? Just wondering whether it is a worthwhile option (extra 2oz).
Most of the time I'll be packing about 20lbs or so (with food), but occasionally (when traveling) I might be lugging up to 35lbs for a bit. At 20lbs I'd guess it probably doesn't make much difference, but at 35?
What difference does the stay make, and at what weights do you like to use it?
