Thanks Smalljaw good to know they are stronger with better quality.
I will have to try some EC 500BP's.
FYI No need to e-mail EC when Barlow's makes choosing hooks easy depending how you search.
Some ways they do this is to show quality pictures of hooks next to a ruler; also by type, manufacturer, size, heavy or light wire and some with approx wire diameters if they get molded.
They also list prices, quantities and if they are in stock.
