I am having the same issues. See photo this was kegged 12 Jan 18. I am now pouring 2 at a time to let the head drop. The photo is after 3 minutes settling. The initial pour is all head. This is with the old liner. On a side note drank 1.5litres Polski Baltic Porter ( was all I was able to salvage after kegging 2 kegs)! It has the new liners with spears. I had to slash the liner numerous times to remove from keg. Coopers need to put some real work into addressing this issue as the liners / head issues will prove to be the demise of a great product.
