Great question. Consider keeping the back long so the hips stay between the wrists like they would be for pencil/arrow/toes straight up. The idea is really staying strong through the back so that the angle of the legs pointing down to release the wraps comes from the slight shift of the hips back initiated from the slight opening of the shoulders into the back angle, less about lowering the hips to get the legs down. This does mean the active flex in the pike is important. And if the pike is not the most closed, using a small circle of the leg out and then towards the chest may get the tail to move off the leg. Also check out the exercise ideas posted to the above question to build the proprioception specific to the skin the cat strength.
