Continentals are a popular patten and many people continue to use them with no problems for Chub.....
Chub have got funny old mouths to get a hook hold... the lips or the inner membrane. the best hook hold is achieved using tiny size 20 or 18 hooks - these seem to find the lip and once in are a bu@@er to get out.
I have used thick wire hooks, but the continentals are very heavy gauge wire for their size. the reason I stopped using them was that because of having a greater cross sectional area, they require more force to 'drive' in.
My perception is that size 6 hooks in smaller gauge wire achieves a more secure hook hold and moves around less - as for the forces involved in straightening a super specialist or similar hook patten - Chub just can't do this - so on balance prefer a lighter patten in sizes 14 - 2......
I am a creature of contradiction though... to fish a whole slice of bread on a hook, you can't beat size 2 Korda wide gape hooks
These hooks have a very wide gape and can accept a whole slice of thick brown hovis (minus the crust) very nicely. Which coincidently I fish on 12lb line straight through to the hook in even the clearest, brightest of conditions......
I know continentals are fine and by reputation are widely used - but I am a subversive and challenge conventional wisdom
