I was casting a 5pc. RPLXi #8 and a #8 GLX this weekend with a buddy. I had a S.A. saltwater taper and as usual the GLX was a lazer gun. Firing tight loops off the tip at the speed of light. My buddy had a line that will remain nameless(very stiff/tan/bonefish). The rod was ok. We switched lines and holy smokes if the GLX felt only ok, and the RPLXi was casting like it should.
This reafirmed for me the huge importance that a line plays with performance. So many people buy a reel and don't seem to care what kind of line the spool up. It makes as much, or more difference than what kind of rod you cast.
I have always wish rod manufacturers would recomend lines for their rods, but there are so many conflicted intrests.
The rod might be the engine, but the line is the car.
I guesse this is obviouse.
