I had an entirely different experience with Jade... not sure why?
I used Pops for several years before I tried a cake of Jade.
The Jade I had was very, very soft (i could squeeze it with my fingers, I could never do this with Pops..further, my Jade never broke or cracked like the Pops had a tendency to do every once in a while). I used it primarily for solo playing. In my case it was VERY sticky before the bow got warmed up. Often too sticky..
Overall I liked it more than Pop's because it gave me extra grip.
Due to it being softer it did leave more residue and there was more cleanup needed.
It also smells like a campfire..
