Still... point being... you're not going to put "little" 250 lb. rounds up on that DR splitter, without hating yourself in the morning.
Roll them up - you're going to muscle the big ones around on a vertical unit as well. I use the tailgate for one half while I whittle the other down.
It's all personnel preference really as I can't stoop on a milk crate without flaring up lower disc but standing and rolling logs I feel no worse - usually better after stacking a c/s/s a full load in a couple hours
