for me pro line evolution ..
a bit like the weiss silverstring, but maybe a little more powerful and better tension stability.
I have a hard time comparing it to alu power, because I am not objective with regard to lux, but I would say that on comfort and power I find it much better, and I would not approach tension stability ! ... (as I play with flexible frames and control, I could not express myself on the control vs aluminum!
among what could come closest to evolution, in similar gauges, it would be: rpm blast, yonex poly tour pro, and signum plasma .. but evo is better everywhere .. in my opinion
the only one that would really come close (especially in terms of softness) it might be yonex poly tour air .. but even on this ground there, I think evo has a little head start, the pre-stretch and the extra power makes evo superior to it ...
if there was only one to choose, i think i would hesitate between scorpion weiss and evo kirsch, but for just the color blue, it will ultimately be evo who will prevail. in my opinion.
