Jim,
You can increase the number of loops ....of coarse material gets used up faster...or you can go to a greater diameter material...say 2# to 4#.

I try to get my leader butt to about 75% the line tip diameter. Area = pi r squared.....the perimeters usually given are... leader butt to be 66% to !00% of the line tip diameter.
Of course there is also the relative stiffness factor.

I think I just further high jacked my own thread.
