Hi @abro,
I do like @lilo.
I’m using a tremendous amount of fields every day (on the forum I say “approx. 20” in order not to scare people lol). I throw some Jing (casual one, not negentropic version yet) in between and it goes fine. I’m rarely overwhelmed. A golden advice that I’ve gotten from forum members.
Also, if you have servitors, they can help you clean the excess/redistribute. Another tip from members which has been hugely useful for me.
As for being physically active in order to drain build-ups, etc. I won’t tell you anything, already knowing that you’re a sportive guy :)
