I am confessing to having too many planes that I do not use. ( i also can think of one or two that I really would use that I do not have :))
my go to scrub plane is an old busted up Bedrock 605 with a cambered iron. I have two or three others that I thought I would use, but I always go for the old Bedrock. Much of the wood I buy is S 2S. So I really do not do a whole lot of scrubbing.
