Just watched this lesson first time. It's funny, I am a natural economy player. I can do alternate picking but it feels a little weird.
My tip to add to
@Brian Haner Sr. lesson: if you are very self aware and had some practice with the exercise you want to learn, it CAN be benefitial to practice with distortion. Because what you focus on then is actually playing very clean and proper muting. If you only play on the clean channel and switch to the distortion you may notice just how much unwanted noise there is while playing. So muting is a beast that definetly needs to be tackled too when practicing speedy licks!
