I use trees all the time to enhance other spirits. S trees should never be enhanced past level 20. I tested it out myself with over 20 S trees and I found that on average that 17-18 is the best. Any higher and the exp is wasted and lower and the tree is wasted. A+ trees are the best at 16-17. Everybody who knows how to stack uses trees for enhancing because most trees gotten from the daily event are not the one that one wants at the time.
