Alan, this is my first year splitting as well so far 10 full cords by hand in the last month and a half made up of elm,maple,birch,beech,aspen,cottonwood,black locust,osage,red and white oak,basically anything I can scrounge,so far hadn't had to cut any of my 5 acre woods.Oh yes and I do wear safety glasses and make my wife and kids do also when they help me.
Started out with a #8 maul and some wedges but now I use mostly a pair of Fiskars splitting axes a #2.25 and #4.25 what they lack in weight they make up with there sharp edge.When I run into problem wood I just buck the piece into 8" instead of 16",haven't found anything that wont split at that size,have a special pile for the small chunks.
I'm not getting rid of the maul just adding to my arsenal so I'm prepared for different situations,might even add a smaller and a bigger maul as time goes on.
My neighbor was almost 80 when he passed away,he burned wood his whole life and split all his wood by hand,he just pecked away at it when he felt like it.When he passed away from cancer he left a 2 year supply split and stacked for his wife.
