Hey, I realise I’m bumping up quite an old thread now but I thought I’d share some progress I’ve made since making the initial post - around a month ago, I fixed what I was struggling with and thought I’d hold off posting anything about it until I’d given it time to settle in (as I often feel like I’ve had a eureka moment only to find it’s not repeatable). I’m not suddenly super amazing at it or anything, however I now feel comfortable with these motions to the point where I feel if I keep practising it in exactly the same way, it will only improve. Basically the technique is there now, it’s down, it’s just a matter of increasing speed through repetition.
So here’s what actually, finally sorted it. I noticed that there were some new videos on the pickslanting primer - just by chance, it happened to be while all of the videos were getting a bit of an update. I watched the “Introduction to Picking Motion” Talking the Code one, and at around 30:35, @Troy talks about the range of motion for wrist deviation, and how it’s more natural to pick from a netural position to ulnar deviation, rather than going up too far to radial deviation. I realised that since trying to do DWPS years ago (having previously been an exclusively UWPS player), I actually subconsciously started doing radial deviation beyond the neutral point when trying to get the pick to escape. It wasn’t to the extent that it was obvious to me however - I could still move within the range, but something always felt off. I just thought that was how DWPS worked and I had to work with it.
Anyway, since watching the video I started thinking about my movements very carefully and basically saying to myself “Do NOT go higher up than this point” - and for everything I played, very consciously putting a block on any form of radial deviation from the neutral position. So downstrokes are down, and upstrokes are more of a “return to neutral” rather than an upstroke. This way of thinking immediately had a positive effect on my picking, and has continued to help me significantly. It also totally explains why I struggled so much to descend with an upstroke!
It’s funny because I was always aware that radial deviation was uncomfortable but somehow as it was fairly subtle never really noticed that I was doing it. Completely eliminating any radial deviation above the neutral point pretty much sorted out my picking, and I would urge anyone else struggling with their picking technique to take a look at whether they’re doing this - even a small amount can mess you up. All you have to to is put your hand in the neutral position, think of downstrokes as a downward movement, and upstrokes as a return to the neutral position rather than a full on up stroke.
