The problem with crossing Lux with a cheaper string is that it takes the magic out of the package. I tried once with Focus Hex 1.23 on crosses and it felt totally different.
I'm still using B5E/PTGP, but I ordered Yonex PTS and HEXtreme to test on mains. PTGP will keep on crosses for now. I also ordered a PTGP black reel so I don't have to use the lime yellow on my Prestiges anymore.
