You need to decide what you’re grinding for then. If you’re grinding for Flezz, go ahead and grind whatever you’re comfortable with. If you’re grinding for Cred to level up, take on a more challenging forum. Pwn whatever you can manage with your store of consumables. Ideally you should end up with no consumables at the end of the day, but cutting some slack and ending with about 5 Smileprin XLs is fine. The aim is to maximize the use of your Flezz in order to rack in more Cred each day, since the more Cred you earn the more Flezz you get in deliveries the next day anyway.
