Helicopter rigs for roach

[woody73b]

Hi all. Just joined the group. I have a question. Been watching and reading alot about helicopter rigs for roach lately. My question bis are these fixed or semi fixed rigs. I bought some korum kits and even when the line is wet the stops feel tight to move. So in a break how would the hooklink slide off ? As in running rig line would pass through the feeder / weight leaving only the hooklink and length of line but I don't see how this would work with Heli rig or am I missing something. Took this picture from article in anglers mail. All help appreciated

I consider them to be semi fixed and so do many waters. I do use the Korum ready to use rigs for roach and anything else but do not regard them as free running. I use a quick change /snap swivel at the end of my main line so I can change the feeder size quickly.
