My experience agrees with this. Namely, I could take nice shavings, but if I wanted to change things a bit, it took much more work than I was used to with my LN planes. Also, there is a big improvement with an after-market blade such as the IBC, Hock, or LN. I have an old Stanly #8 that I use. The plane is fit with a LN blade and chip-breaker. There are still some annoying issues with it sometimes, but, I don't adjust it as much as some of the other planes (like my #5).
