The Mavic CXP22's are a perfectly acceptable rim. At 510 grams they are neither heavy, nor light. Most clydes would be on rims of around 430 grams to 585 grams. So, they're right in the middle. This might explain the LBS' suggestion of a very light rim if you want to actually "notice" a difference in your wheels. 130 grams of rotating weight per wheel might actually be noticable.
However, your tires could easily save you more weight than that and at a fraction of the cost. The Hutchinson Crosstown 700X32 are listed at 650 grams. Depending upon what you consider a "cycle path" you could save as much as 400 grams per wheel by substituting lighter, narrower tires that will also roll with less resistance.
Your "cycle paths", are they paved? Are they graded gravel (like a rail trail)? Or, are they dirt, rock and mud?
