The proper form
The "proper" form does not work for everyone.
As a coach, I have to remind people that any form change will not feel right for a few months. You can't make a major change without honest effort.
The first thing is too make sure you have the proper draw length. A pro shop can get you close, but a "coach" will make minute adjustment if needed. A "T" formation is basically what you want in a person's form, but sometimes it just doesn't work, so you tweek the form already in use. Sometimes it can be a simple as a thumb placement to correct lefts and rights. Sometimes changing too a different stabilizer for better balance. It's not always about changing your form.
Helped or confused even more? Form is the most important aspect of better shooting. I used to shoot 296/36x with a hunting setup and fingers. Form Form Form...and a little bit of help.
