Whats the fastest sinking leader out there?? I heard of learders being made of titanium, this true? I want one that sinks like a rock.

Thanks,
Jeff

I generally use Airflo Salmon/Steelhead 10' polyleaders; Super extra-fast Sinking. They're tapered to cast easy, as a shooting head. However, if you really want to get down in a hurry, RIO T14 sinks at 7-9 fps; and T17 at 10 fps.
T14 & T17 are clumsey to cast, but 10' of either will get down like an anchor.
You can by it by the foot @ about $1/ft.
