Hey Carol- welcome back! And what a star Alex is trying to help put like that.
Sounds like the rest of your trip was good though!
Tim, yes Alex spent some time on it and was most helpful - this was even though he was busy diving with the guys in the warm, balmy waters of Port Hardy BC...
I do thank him!
Glad you had a good rest of your stay up in Port Hardy. Hope that the weather improved.
Alex
Thanks Alex, I had an awesome time!! I'll be posting something on it soon. The weather got worse - then got gorgeous - then a little bit worse - then beautiful for two days - then drizzle - such is British Columbia...... Funny thing was when it was at its worst a diver who I buddied with, Valerie, and then Jett joined in spurred on by John and we started cooking up some interesting scenarios - funny what too much rain will do to divers......!! 
Yes Alex my port on the D3 looks like it did on my ND20 - I even attached the 5T or 6T w/o the black ring and used blue tak and there was ample room for it all with the ND20 and Subal 105vr port. But as you say it doesn't fit or work on my ND30.
Good news Alex and Tim is I spent a lot more time on w/a than I would have, the viz was so great and when the sun came out I exclusively used the 10-17 and tried different things like diving and photographing in only the top 10 feet of water for 50 minutes, etc. So sometimes a forced change in lenses can bring out good things? Well that will remain to be seen but I do know Jett liked some of my w/a. I'll post some soon as soon as I get caught up on wonderful stuff like laundry (still on vaca but some things just don't wait......!)
I'm diving with Jan (Honza)the day after tomorrow and my husband is meeting me here in Washington also for the journey back - so lots still to come. I don't think anything is quite as busy and as much work as a vacation!!! 
Thanks for all the help, Carol
