Same for me. I shoot for a split size that allows at least a dozen splits in the princess firebox. That means 3-5" splits for me. Yes, I too have evolved over the years. I don't split a mix of sizes but my average split size has dropped to 3-5 for next year's wood that was split this summer.
Loaded the stove with 6 splits this morning. I won't even get into the "big" stuff for the next year or two. Had some room for a filler or two but not needed for 12-15 hour loads.
