I've been using the Hydro Tech 5.5" pads on my Griot's DA for the last couple months. The Cyan combined with 205 is my one step and finishes LSP ready imo. However, once the pads are used for a few panels, or maybe half a car, they are useless. They separate from the backing plate, wobble a lot due to a poor cut, get soft and soaked quickly, basically they are only good brand new and clean, and only for a short amount of time. Rubbing a microfiber towel on it to clean it inbetween panels only hastens the foam failure, it actually does damage it.
I'd be absolutely thrilled if anyone has a better alternative, as I am ordering 6 pads every week for the last two months as they have such a short life span. I used CCS in the past but the HT Cyan just finishes down too well to go back to the CCS.
