Based on the Selector tools, Option #1 is the Chromesoft, and Option #2 is the Chromesoft X. If I adjust parameters just a bit they can switch spots. I usually lean to the X type of ball from various manufacturers, but may need to test these side by side.
I'm playing the ERC Soft this weekend. I have played a Truvis in the past. I want to see how the ERC performs for me.
