Oh yeah, so a little tiny discovery the other day when changing to the light weight headlamp buckets. My original retaining rings were smaller in diameter and lighter by a few grams or so. Ha.
Big rings were good for 1.80 ounces each, the smaller 1.20 ounces each. Whoo-hoo. LOL.
In all seriousness, at this juncture in my "Every ounce counts" campaign, all the work, hunting and buying for a fractional 1-1/2 lb savings that the headlamps gives me is Kosher in my book.
