I'll dare to say that in any sport, efficiency of movement wins out over any other factor. The more efficient you are the less energy your wasting trying to overcome inefficiencies. Unless you can shave 4-5kg off your bikes weight, a kg or two isn't going to make a bit of difference. Thankfully, a lot of riders can probably shed 5kg off their midsection with relatively little effort and that will make a difference in efficiency and getting up the hill.
