What ULCS arm with ikelite ds125

Hello everyone,

I am just getting into underwater photography "seriously" I have purchased an ikelite housing for my canon digital rebel xt with a 8" dome and the tokina 10-17 lens. Obviously I am looking to do more wide angle stuff initially. I like the ultralight control systems but am unsure of what size arm would be best for me. I am planning on getting one ikelite ds125 strobe. What is the best size for wide angle? What does everyone think of the ULCS system? and also I am not entirely sure what exactly I will need for the whole arm set up to connect it to my housing and the strobe can anyone point me in the right direction? Thanks for the help!

Most people will say 2x 8" (enough) or 2x 12" (really wide). I use ikelite with 8" and 10-17mm and short arms most of the time will lead you to nasty backscatter.

I had been using 2x12" buoyancy arms, bulky but with decent results.
