Corrugated or not?

This one is my 24" long #31 Jointer plane..

Weighs about half of what my old Stanley No. 8c did.
The larger iron planes I have, have grooved soles. #7c, # 6c, and a #5c. Since I tend to skew them just a hair, never had a problem with the grooves. The grooves do make flattening the soles a bit easier...less iron to remove.

Have both a #7, and a #5 in both grooved and non-grooved models.....no difference that I can tell. Other than candle wax tends to build up in the grooves.....

Well, to throw it out there, I ran upon an old wooden 26" jointer from Ohio tool co. for $20. It now sits in the workshop waiting for restoration ( it barely needs any) and for me to find a metal buddy to sit beside. I wouldn't mind a transitional plane, but I would rather have a wooden and metal plane for occasions where I only need one of the two. And by the way, ever since I made that beader I posted about, I've been riled up about making another. So I might be showing up here in the next month or so with one. Happy Fourth of July everybody.
