Thanks for the compliments on my rig.
I have to say that I rely 50/50 on memory and reading so I find the Music Pad Pro to be a great alternative to the heavy homemade fakebook+music stand+light that I used to carry. Don't forget that my MPP is also serving as my accompaniment MP3 player at times too, plus it helps illuminate me on stage! It's serving many purposes in my rig.
Whether or not to use music on stage is a personal choice and I see that some top performers use written music while others do not. Like DonM I play 5-7 nights a week sometimes twice in a day and take requests from a list of hundreds of selections so whatever makes my job easier is fair game.
