I just packed my LowePro roller bag.
1-Complete Ikelite housing for the D-200 with ports for 60mm and 105MM, UCLS tray, 4 9" STIX arms and clamps, 2 Ikelite Ds-125 strobes and 2 Ikelite chargers, 3 Ikelite batteries and Ikelite dual and single strobe cord.
2-Complete Seatool housing for the D-300 complete with Seatool tray, 4 9" STIX arms and clamps and 2 INON Z-240 strobes. Ports for 60mm and 105mm
3-Complete Olympus housing for the e-330 with UCLS tray, Athena ttl converter plus Athena TTl converter and cord plus backup cord, UCLS arms (2) with stix floats and clamps and INON Z-240 strobe.
4-Various tools and housing cleaning stuff and multiple backup O rings plus an aluminum block and (2) Ikelite cords to convert Ikelite dual strobe setup for use with athena on the E-330 setup.
Everything is carefully packed and protected using the lowepro dividers and foam. I am off to Bali and Wakatobi in March with three complete camera setups. My wife and I have learned that a spare is necessary.
The only pieces of camera equipment I couldnt get in was the 8" Ikelite dome and the AA rechargable batteries and chargers. I still have room and am up to only 63 pounds so I can get another 7 pounds in the outside pocket.
Solution: Be an elite flyer on Continental or fly fitst class. What's the problem?.........Oh.......and find a scuba diving, picture taking wife that made lots of money and received a generous retirement. It's not so hard and she's pretty too.
