Help with a HOYA HSM CP filter

I just need some help I need to pick up an Hoya CP filter,but cant really decide between an HSM and Pro 1? I know there is google but could you guys do the educating here or suggesting.

I know there is a coating layers difference but between the two any big big differences ? I need it for an outdoor pool shoot for my 24-70

Go with Hoya HD. Make your money last and buy a tough filter.

Ended up picking up the Hoya CP HMC, they were out of HD and I felt like the HMC would be a bit better than the Pro 1.

But they did tell me an HD filter is a nice $250
