Hi Julien! Thanks for posting. In general, you’re not making a pickslanting movement, and that is why you are a speed-limited. You have habituated a movement with a curved trajectory, and it may be difficult for you to feel that you are doing this and to change it. We can debate whether this is “crosspicking” or something else, but the fact that you can’t do it fast tells me all that really matters, which is that it’s not working.
Have you worked through the “getting started” material yet?

Take a look at this when you get a chance and see if you can follow along with the “goals” on each page. In particular, try and reproduce the picking motions in the “Introduction to Picking Motion” talk. Don’t use a metronome for this. It’s just going to trigger your current motion which is already completely learned. Instead, try to “go fast” while trying to do the new motion you are testing.
When you do these tests, film yourself in 120fps and verify that the pick really is moving in a straight line from trapped to escaped and back. If you can’t go fast, and the slow motion video shows curved movement like in the clips you posted here, then the test failed. Change something about your form or motion path and try again. The idea is to do it correctly by using speed to force your body to find the most natural way, and to try and memorize what this feels like so you can do it again consciously.
One thing that players report about learning pickslanting movements is that rest strokes can help tell your brain what “straight line” movement feels like. For dwps movements, the downstroke is the rest stroke. For uwps movements, it’s the upstroke. Hitting the string can make the movement feel different then your current learned movement, and that can help you break the habit.
Fyi, when posting youTube links, don’t use the link function. Just paste the URL on a separate line with a blank space before and after - the forum will expand into an embedded video right in the thread.
Again, thanks for posting.
