As you lengthened the CS and changed the dropouts, you likely affected the BB Drop, STA, HTA and Trail as well. Enough to notice? Probably not individually but, 10mm here, .25* there and another .25* up there all adds up. The very small changes, when added together can have a dramatic affect. The trick is knowing which small changes to make to accomplish the goals for the bike.
I'm reading a book right now about how the brain tricks itself to make sense of the world it perceives. It turns out there is psychologic phenomena that causes the body to feel what the brain thinks it should feel - sort of like confirmation bias but, different...so, who knows.
If you like it, ride it!
Happy Friday.
