Leader material for 4lb fireline

[Struth]

Any suggestions for good leader material for 4-6lb Fireline. Currently using 12lb Vanish or 12 lb Tortue mono. I find the former has unreliable knot strength while the latter is not low vis (but very tough). Any opinions on Siglon or Stren Magnathin?

I fish around racks/rocks/sand and encounter both bream and lizards.

Cheers

Give the Penn 10x a go. I use it for leaders on various sizes of bradi that I run. Good knots strength & the best abrasion resistance on the market.

Cheers,
