using a rotary isn't hard. i first used one when i was 14. it was a one speed, 1750rpm black and decker automobile rotary. it was a simple concept and after a single car my techniques was already 100x better. at first you may try to fight the rotary but you will eventually just work into a grove and feel the proper way to do it. it almost has very little to do with your sense of sight or sound.
i know that you can do damage with a rotary but really more people shouldn't be so hesitant to use them. it doesn't really take hundreds of cars to learn like a lot of people around here say. you will keep getting better but you will also do a fairly good job in no time.
also i think red is a very nice color to learn on. its not as difficult as black so you will build confidence yet it is still fairly easy to see swirls. the first car i ever used a rotary on was a red pickup truck and i was damn proud.
