Hi Johannes,
I think I do feel myself getting trapped but have so far chalked it up to lack of practice with this technique because of what Troy Said in the post Joe referenced. Joe had mentioned in that post that he thought I should (pronate? supinate?) my forearm to bring the thumb side of my hand down to the bridge (assuming I understood that correctly). I do like that idea of giving myself a more neutral pickslant so I have played with that idea a bit but have struggled for various reasons.
Troy says my method should be good, I think because there are people who use it well. However, I’m wondering if bringing my thumb side down would make playing cleanly easier or if it really is important to use the technique that feels most natural and build off that.
