Hi uiuc_josh,
Thanks for the update 
It’s not unusual for people to be surprised at the softness of latex even in the medium range even though others are surprised at its firmness. It’s one of those things that depends on the “species of softness” that people are referring to or most sensitive to.
I also think that layer or core exchanges are a great idea … and so much better than starting all over again
I’m looking forward to your next report when you’ve had the chance to sleep on your new layers for a while.
