leepix,
YES, hard wired TTL cord with Ikelite circuitry equipped housing and DS strobe is the way to go IMHO with Canon G11.
As crawdad says you CAN go into MENU in Av or Tv mode and switch your flash control to MANUAL which gives you the same 1/3 , 2/3 or FULL power adjustments under FUNC choices like in M shooting mode. I shoot TTL flash with sensors that duplicate it so I would never do that. But you can....
As far as adding an optical cord to sensors? I wish for a "light pipe" flexible white "tube" I can slip on the sensor front and direct right to the top of my housing where the flash bounces out of. I sure don't want a cord getting in the way of me being able to constantly adjust my strobe angles.
Currently the reflected flash works fine as long as I'm away from other photogs who might set off my flashes. Before a dive I tell them to motion for me to turn mine off when they want to take a pic of me. Not a big problem at least for me as I'm usually shooting alone anyway ![]()
With a bit of luck you can take pics of another photographer shooting as below.
YMMV
