Good observations! Country players who want their fingers to be “on deck”, as Andy Wood likes to say, i.e. on deck as in ready to go for hybrid when they need it, do use a less obvious arm position. Let’s call it “less obvious” because from this arm position you can still have access to any kind of pickstroke, either downstroke escape or upstroke escape. Also, from this arm position the slant of the pick won’t be so visible. So looking at the pick and thinking it’s neutral or straight up and down is normal / common.
Instead, the way the pick is moving is the best way to understand what kind of motion you are making. i.e. Does the pick go up in the air when you play a downstroke, when you play an upstroke, or both? That tells you what kind of motion you’re making. When most people go fast, they have one default motion that they click into, and it’s usually either upstroke escape (i.e. upstroke in the air) or downstroke escape (downstroke in the air).
From there, if you use wrist motion, the new wrist motion section has the most step-by-step instructions for getting these movements to happen. Even if you’re already doing one of these, it can help to understand exactly what you’re doing, since most of us learned this stuff subconsciously. We put the upstroke escape chapter on YT. The downstroke escape chapter is in the product, as are some other thoughts about speed and lots of thoughts about getting your grip and arm position set up.
As part of this, I think taking a look at your grip is a good idea, and even trying more than one grip, as a way of shaking the tree a little. The pick grip section of the Primer has most of what we know on that subject, and then the wrist motion section revisits that again just as a refresher.
After that, it’s hand synchronization via chunking, as we talked about before.
