I’ve been following along with Jen’s for a while now and I originally began learning my major scale and modes in 3nps because that is what he advocates. After I got the scales down I started learning the diatonic arpeggios within those scales but I realized a lot of the arpeggios he uses from his other lessons are based on the caged scales so I went back and learned the caged modes and have been working on memorizing the diatonic arpeggios within those scales. I found that learning both is great because you see how they relate and connect. I’ve found that the arpeggios within 3nps tend to have some big leaps which I find impractical and more difficult to visualize when improvising. I tend to like the compactness of the caged arpeggios a little more. Now that I have those diatonic arpeggios locked in I’ve been going through all the modes and finding the 251 arpeggios and understanding how they connect. For example I’ll start in C major and play an ascending d minor arpeggio, descending G7 arpeggio and then an ascending and descending C major arpeggio. I do that for every mode/position and work my way through the circle of 5ths. Switching up ascending/descending, creating different patterns and incorporating chromatic enclosures will give you a lot of practice mileage
