Index release issue

[qboss]

Currently using a TRU Ball Beast XT index release but having an issue of getting a consistent finger warp on the trigger while keeping the same anchor each time. It seems that the trigger will twist slightly making it hard to get my finger wrapped around it when it does. I am not sure if this is due to my form or my release set up. Would a change to my form or moving to a thumb release fix this issue and help me be consistent?
