Any chance you can make it to my class tommorrow or Thursday. I'd love to go over this live with you. My first impression is that bag is too small for you. I'd love to see you tuck the back further back but as soon as you do, your wrist bend as the neck of the bag is too short. How tall are you?
Everything else here looks great, good tuning and steadiness. I'd love to workshop the bag posture with you just a little before we move on here and certainly before you considered changing bags! If you can't make it to my morning class just let me know and I'll try to make some other time to meet with you.
Looking forward to talking about this more.
