No problems here! Any thoughts toward a solution are great!
I do separate the top patch from the middle ones but mostly to get the head of the spinnaker at the opening (IMHO, the top patch is too close to the head and sucks the head of the sail well inside the bag if left alone).
I do need to try and separate the middle snuff points.
Sock is plenty tight and spread out at the back.
My F18 spinnaker snuffs very easily - this N20 mid pole is ridiculous by comparison.
