Knopfler
The cleverest woodpecker in all of Yorkshire!
The three four 'P's for me - Prolific, Pinecone, Panelbase and Populus.
Far and few between them all, due to my demongraphics no doubt but still my favs.
Haven't subscribed to many more though. YouGov I have been doing for over 2 years now and STILL not got to £50 (I haven't done them every time though but just stepped up recently so I can get to £50 and then never have to do another one!).
Not had one from Populus for a while though I always do them.
