Thanks for the feedback - my setup is a bit unusual I guess, as for the 2nd bike it has a Shimano STePS Middrive, so I need a really strong 10-Speed chain (for the width). At 118 links, the existing chain has the derailleur jockey wheels very far forward - a little too far for my liking. 116 would be impossible (I checked). I’d actually prefer to lengthen it to 120 links to have the derailleur a little more relaxed.
From a geometry standpoint, the chain is under tremendous additional load by having the jockey wheels near horizontal - it takes very little downward pressure in that configuration to apply tensile forces. When the jockey wheels are vertical, the opposite is true.
