From my limited classical experience, I found Bach to be the best for the bass. He seems to be pretty straight forward 8th notes from beginning to end (for the most part).
The thing I've discovered though is there's so much more to memorize with classical; it doesn't repeat over and over like rock. It appears every measure through-out the songs are different, but I haven't delved too deeply and I'm sure others have a better insight than I do
