ZEN 100 or 200 for Dolphin UW shooting

Any thoughts on using the mini-dome Zen 100 or 200 on a Nauticam D300s housing for shooting Dolphins with either a Tokina 10-17mm and 10,5mm NIKON ?

Thanks, maluco

The dolphins (in fact all of the images) here are taken through the Anthis/Nexus mini-dome, which I think was the first of the small fisheye domes. Some of the sharks are taken with a Nikon 10.5mm, some with a teleconverter, but the dolphins are all with a Tokina 10-17mm:

They're not as impressive as Frank(rabbit fish)'s images in the thread:

Frank was using a traditional large dome with the dolphins, and if you look closely at my images you can see Alex and his large Zen dome in the background of some of the images...
