Have you tried a transitional yet? Wooden sole plus fine adjustment.As I fell in love with my antique wood jointer, I am almost afraid to try a wood smoother. I think precision adjustment is more important on a smoother, so sticking iron.
My #3C and #65 block planes are I use the most. The older I get the better the #3C works for me.Already have a #3 with a corrugated sole but bought another today anyway.
After all, having more planes increases the odds of picking up one that is sharp.
