When looking at gear, does the size of something ever trump your weight guidelines?
For example, I'm looking for a cup. I see two decent options - REI Ti Ware Sierra Cup (1.6 oz) or the Sea To Summit X-Mug (2.4 oz). This isn't a very good example, because a) a cup isn't 100% necessary and b) either one would fit in a pot (I think), but you get the idea. Anyways - the X-Mug weight slightly more, but it collapses to a flat object, only .5 inches thick.
So, I'm sure you kind of get the idea. Does the size of something ever influence your decision more than weight?
