Here's another way to sequence the Minor 7th arpeggio. In this case and Am7. I am using stretching, picking and hammer-ons and pull-offs. The stretching is only scary in the beginning. If you decide to ONLY play things that requires you to stretch beyond the classical traditional fingering style for an entire week - it will already seem like second nature to you. The key is to not playing anything but that for an extended period of time.
