I doubt I would actually have enough prepared repertoire that’s performance ready to go and play on a stage tomorrow.
As for what I would use, I have several different movements that I use situationally.
My “default” mode is reverse dart-thrower movement from a loose leading edge grip, which I can use for mixed escape alternate picking, two-way economy or hybrid/swybrid picking. If I need continuous DBX, I can tuck my fingers slightly, supinate just a little bit more a Andy Wood style 9-0-2 DBX movement (this is my primary technique on acoustic guitar). The basic form is capable of continuous DSX, but I don’t have much DSX vocabulary that doesn’t incorporate hybrid picking.
This is the mode of picking I use when learning most things. It’s highly versatile, plenty fast for most applications and works well with my legato technique. It’s mostly independently developed, but I’ve definitely incorporated some some things from watching and listening to Marshall Harrison, Anton Oparin and Andy Wood.
For my own personal vocabularly, I mostly use USX. From the same grip as my default, I can switch into a continuous USX form. I developed this from studying Eric Johnson’s form. This form is super reliable for me and it’s my favourite picking movement in terms of tone and articulation.
Alternatively, I can switch to a Shawn Lane style trailing edge grip and use a dart-thrower USX mechanic. I trained this movement during the pandemic, and it’s already the fastest movement I can do. It has some cool advantages beyond just speed. Unlike a more supinated USX form which requires that the fingers be tucked on the pickguard, the more neutral position means that the middle finger is always available for hybrid picking (even at silly speeds). This facilitates more ways to create repeating coordinations with odd numbers of notes, and it allows for some vocaularly with string skips that would just be infeasible any other way. Instead of hybrid picking, I can also hold a vibrato bar and pick fast without obstruction, which I can’t do comfortably with my other forms.
I can do other movements too. I can do the Molly Tuttle style 10-0-3 movement decently well and I can do a fast thumb/finger USX motion, but I don’t really use either except when demonstrating in lessons. I can’t do DSX elbow well or elbow hyperpicking (can only trigger the movement occasionally), and I can’t do the Gypsy form.
I’m finally satisfied with what I have, I don’t plan on learning any other movements, and if the movements I don’t use decay in time I won’t be upset about it. I may eventually need a shoulder surgery (I had a dislocation in 2020), so hopefully at least one of the movements I use remains mostly functional for the rest of my life.
