The vast majority of cue sheets are in a font that is too small for me to read easily. I've found I much prefer to follow the "pink" line on my eTrek 20 instead. But I do want to know where the next control is as well as what the name of the business is. I recently got a top tube phone/snack holder that works perfect to hold a custom cue sheet I create with the relevant information about controls. I do carry the full cue sheet in my pocket just in case technology fails me.
