White lightning may be great stuff but it has caused no end of bother to me when trying to web search info on my bike which is a Raleigh White Lightning. All searches return never ending info on this lube Rolling Eyes
1989 - the year they must have accidentally employed a tramp in the marketing department. Out went the lightweight models named after mountain ranges, in came the range named after types of booze that really mess you up - Moonshine, White Lightning etc.. It was a short-lived renaming (the bikes were the same, just new graphics and names) as the Dynatech's were launched very soon after.
In response to the original question - yes, wheels, wheels, wheels. A saving in rotational weight is worth the square of the same saving made elsewhere. Your bike will go, stop and steer better. The only thing you might notice is if you have really chunky wheels today you lose the 'flywheel' effect a bit, which I used to use to plough blindly through trail obstacles. My friends thought I was brave and skilled, in truth I couldn't stop the bugger.
