No chance to compare my CSC3 to PS2 yet... Anyway, I went through deep puddles at 50-60km/h on BORR (Butterworth Outer Ring Road) on Sunday night, car was rock steady, none of those feeling that the steering is being tugged to one side. The parallel grooves on the CSC3 are really wide, so I think they can channel water away effectively. But whether such wide grooves caused the contact patch surface area to be reduced in dry weather grip remains to be seen...
