Thanks! And well spotted! I’m glad to finally find someone (Teemu) who has the same thumb as me! I was always spotting the huge man-thumb knuckles on the likes of Steve Vai et al. and wondering if I was at a structural disadvantage.
The only difference with Teemu is his anchored fingers, compared to mine - closed.
Tracking! You might be on to my problem here. I have not given that much attention… so back to my tower I go.
Apologies for the confusion. By “flopping” I’m referring to the occasional missing of the target string, or the accidental (thankfully muted) hitting of neighbouring ones (the whole point of pickslanting is to avoid this), or not fully achieving a clear-sounding, properly picked note (often on the upstrokes). The journey of the pick should be absolutely consistent in this exercise… yet for some reason it goes a little too vertical (or something) every now and then. That’s what I mean by flopping - occasional mistakes.
I later (confusingly) mentioned my thumb “flopping” too… in that case, I meant that I have benefitted from learning to keep it absolutely relaxed and still… to focus on isolated, basic, correct DWPS movement, before advancing to anything more advanced.
