A few years ago I bought a LN 4 1/2 at a hand tool event. I love it and use it for my present small scale work of boxes, edge jointing and flattening relatively small panels. It is heavy at 5 1/2 pounds. I'm thinking I should have gotten the #4 cast iron. At 4 pounds it sounds more manageable.
I was going to go to the Oct. 10-11 tool event here to try it, but will not be able to attend. Has anyone personally addressed this question? (I recall the woman demonstrator expressing her preference for the 4 1/2 over the 4. I probably outweighed her by 50 + pounds. So much for equating strength and size).
