I disagree with this statement. After running the 80-140 for three months and then changing to the light grease I can already feel a difference in the way the bike rides. It is not sluggish, ie feeling like I am running up a 12% grade in 30/25 while sitting. This was my normal run. The pawls are noisier, but I can live with that if it will be less sluggish.
