Oh lawdy, we gotz another FR bot nit in the making.I think its fine to limp behind with small/mid SCs like 56s-89s or whatever and small PPs in position, but definitely don't open limp with them. Axs, is also fine to limp behind but you can definitely raise it pre if its only like one limper and you're in LP. Isolation isn't just for 6m!
Good luck with the switch and make some mannies this month ffs.
