I learned them both (no more tears/moma...) and it isn´t hard at all. However I don´t find No More Tears album as good as Blizzard, Madman and Wicked. Zakks best stuff is on Wicked (I haven´t heard the new one a lot) and songs like Miracle Man, Devils Daughter, Bloodbath In Paradise and Tattooed Dancer kick ass. Solos are not that hard, pretty much like Metallica but they are better. Zakk has an amazing picking technique wich is pretty hard to nail down but after a while it goes. His rythms are amazing too.
