Perhaps this 'wide gape' is more trouble than it is worth but it is one of the reasons PP recommends the Classic Spider !
I have used the now defunked Drennen Wide Gape Maggot Hook for years, landing tench to 7 pounds on a size 20 barbless, so I am a fan of wide gapes. If I can find any more of these hooks I will buy them as they are spot on for spiders.
Here is an image of Specimen version, thicker wire but the same shape.
I wonder if I have a bad batch of Partridge hooks, it would not be the first time in a long way. I work with the sister in law of MArk Hamnett of Partridge, perhaps I should send him some examples for his opinion
