For the average cyclist, even a change to a lighter set of wheels can be felt almost immediately. It feels 'lighter', your ability to generate speed is quicker. And in a race/criterium situation, this becomes even more important with constant changes in speed.
There however comes a point when the cost benefit ratio of a set of wheels become ridiculous. Here's a list from weight weenie with the highlighted bits of what I deem the most cost effective set of clinchers.
Yours dun fair too badly down the list Mike but with a set of 202/303 tubs weighing less than 1100g, its something to consider.
