yeah that guide is fine. there are a lot of small variations you can do too, such as 100% supreme/rex and running upstairs after supreme to get prime off you so you can ss rex; pure tribriding all 3 (ccbow is highly recommended for this); supreme-rex-prime-til-redbarred-rex-prime(KO)-supreme. you can also put the cannon under supreme. cannon works a lot better on supreme than prime because prime has huge defense. you get less kills per hour but it's safer, and still more kills/hr than normal 2.5/trib a lot of the nuances come down to your own playstyle. are you looking for high profit, short trips, and lots of clicking, or lower profit, longer trips, and less clicking?
