Just for perspective and to bring science into this.
Weight: 150 grams vs 124 grams
Blade weight at full stride extension: 600 grams vs 496 grams
Average strides per game: 1000
Blade weight transferred per game: 600kg vs 496kg
600kg - 496kg = 104kg less weight transferred per game which equals 229lbs.
That's with comparing 26 grams of weight difference. Now imagine 200 grams.
