Your joking right? Last week I split some 32", wet, wavy grained elm that just about done the 35 ton Speeco in. Most of the splits were half split and half cut to get to the bottom of the stroke. You want to talk moaning and groaning coming from the splitter this stuff had it in spades. I won't even go into my moaning and groaning. I agree 100% with the other posters that stated if your splitter won't do it it may be time to look into a new splitter.
