What I can tell you about the SR 300: it goes LONG. The high RG really delays action, and the ball is ideal for direct attacks on the pocket on medium oil.
I do not have a The One as reference, but a Shock & Awe which has similar core specs and reaction properties. My S&A covers, with a similar drilling (pin slightly higher and further way from PAP) more boards and breaks about 5' earlier than my SR300 on the same conditions. Both can be used on the same conditions, but the SR 300 is an excellent choice when the track starts burning up in the heads. It delivers its energy late but effectively, it should be a great complement to the lower RG The One. With some polish, I guess you can use the SR 300 even on lighter conditiosn and late games.
Go for it! You might also check my review on the ball in the Ebonite section (Video included).
