Alan,
I too have that same plane and while I do speak plane,:lol: I personally don't use it all that much. I have a series of planes ranging from a LN 103 to a 605 bedrock and also a LV shoulder plane. Of the group, I find myself reaching for either the LN 103, 604, 605 or the shoulder plane. On rare occassion, I do use the rabbet block but probably could do without it. If I had to pick a goto all around plane, the little bronze 103 would be at the top. Small enough to hold in one hand but packs a lot of wallop when used properly. Naturally you won't find me doing any face planing with it but for trimming and trueing, it can't be beat in my opinion. Your mileage may vary though.
