To me watching something like this throws up a few points .
Is it a good idea to fish a pop up that is totally different to the freebies around it ?
Having the pop up close to the hook may well end up in you missing a larger fish , ( larger the fish larger the mouth , more chance of the fish just blowing everything clear away )
That using a bottom bait that has been critically balanced ( drilled and cork inserted ) may be a better than a very buoyant ready made pop up.
The way a fish feeds ( and unless you are able to watch this there is nothing you can do about it ) will make a huge difference to how many times it will get caught .
