In reply to the sheep:
> For me dropping weight off the rider is far more likely to result in significant difference compared to what you can save on a tyre
You have to laugh at cyclists / climbers who have spent small fortunes to save just a few ounces, who looking at them could easily lose a stone in weight.
Its worthwhile if your an elite athlete, but if you are an elite your likely not to have an ounce to spare, and if your not, you can easily lose more weight than you can ever afford to save by using super light equipment.
