For Wally and Billy (and other Sage experts) - Sage fly lines
 

I'm about to buy some new fly lines, and except for some wulff TT and LB
lines (and one Sage SPL line) , use SA mastery or XPS lines. How does this
Sage fly fline compare. Most usage will be on a Sage SP or SLT but might see
some use on a Winston IM6 and T&T Heritage series.

Thanks
