Ja die eerste een, plain mono leader is the one I was told to use by my skipper 2 years back, stuff has not let me down in the rocks and reefs etc.. and I'm still very happily using it. Use it in .35 to 1.2mm and no complaints whatsoever.. Generally using .35 for bass and kurper, .7 for leeries, .8 for bottoms and 1.00 and 1.2mm for heavy spinning from bricks and boat depending of what is on and the fish of the day.
