i can't imagine bigger being easier to split than smaller.. just looking at weight issue and all.
with a friend and a 'here hold this and stay out of the way' helper, I had that 2240 split in about 2 hours, after fighting with the hydro lines on the right side.
that was in a nice enclosed shop with concrete floor, overhead hoist, lotsa floor jacks and stands.
my shop's got none of that. :)
I'll be lucky if I can use my stepdads shop... :)
