The LOOPs are definitely faster than the Sage rods. The Blues are fast, Greens faster still.
What is the intended application for your new rod? Since you have both a 13-1/2ft and 14ft rod, in which situations do you envision using your new rod the most? This information will help me make a recommendation for you.
Since both rods are 9 weights, I tend to use the 9132 on relatively smaller waters compared to the places I use the 9140 blue. Also, I tend to use the 9132 with shooting heads (shorter rod=shorter head length) and the 9140 with somewhat longer belly lines like the Quattro.
