What lead to use under the rip bridge

[Belligero]

Hi Guys,

Taking the boat out Friday night for hopefully a jewie. Conditions and tide may not be right but it's a comp this weekend so I want to make the effort.

I'm a little worried about what sinker I need to use. As I'll be anchored around the rip bridge I'll need something heavy otherwise the current will be too strong for me to find the bottom. It's also 20ft - 100ft deep!

Should I be using something like a snapper sinker or rather a large ball sinker?

Cheers
