Your Expert Advice, Please: D100 vs CP8400

I stepped from my Nikon CP5k to the 8400, selling my housing but retaining my 2 Ikelite DS-120 with Ultra-Light arms.

I now have the CP8400 and my D100 with 14, 17-35, 35-70, 60Macro, and 105 Macro lens to choose from.

I am fortunate enough to be faced with a high class problem:

Which Ikelite housing should I buy for a June trip? If y'all recommend the D100, then which lens for all around shooing. I know the 60 is razor sharp but will it share a port with the 17-35.

This board is full of experts and I need your expertise!

Thanks in advance!
