just switched form 12x KC pro's. and i have fallen in love them. love how you get the stiffness you want in any mold. SSS is what i am throwing. would love to try a Chalky one.
If you want a chalky SSS you'll probably have to find one at Gotta Go Gotta Throw. The new chalky runs like those on Marshall Street are quite a bit stiffer and not as grippy in my opinion. Still nice, but the pale orange ones from older runs are awesomely grippy. Pale orange below is SSS and pinkish orange below is stiffer, newer run.
