I had another housing and went with the SRP and screw on filters and have not been sorry. Great optics and as soon as the new red filter is available I think it will be the perfect system for the GoPro. Add the SRP tray and arms, a couple lights, and it is an excellent compact video system. I can put it all, including the lights, in a regulator bag! Here is some video from Fiji at about 35-40ft deep:
