The "Kris Kross" reference was unexpected and great. Guess I'm not the only one who says that when it's time to do something. Dude is a product of the 80/90's like myself. Respect.
One i always liked doing for dexterity....the same 4 note per string chromatic thing....but keep each finger on the note until its needed on the next string....descending gets whacky haha. But does great for building the individual finger dexterity. Try to let the strings ring freely.
