Well poop. I bought a yellow KC Pro Roc 176g and a yellow DX Roc 170 and used them 4 rounds this weekend. The problem is I don't want to throw anything else. What am I going to do with my other 64 midranges?
Thanks for the tip on getting yellow. The yellow KC Pro plastic is way more grippy than the white KC Pro Aviar I tried and the yellow DX is holding up great. Comparing the profiles, neither one is flat and the tops above the PL are the same. On the KC Pro the rim slants in directly below the PL, while on the DX the rim is more blunt before slanting in. Strange if they're coming from the same mold but this makes the KC Pro more overstable. KC on right.
I'm going to resist buying any more Rancho Rocs until XT is released for retail. I'm betting that one will be my dream mid.
