Thought I'd share this little mod I did to my A7D. While I have nothing but praise for the handling and ergonomics of my new Aquatica, I've always missed the hand strap that was on my previous Subals. The strap was awesome in helping one-handed shooting if you had to steady yourself with your other hand, plus it allowed the shooter to relax the right hand and not have a death grip when shooting one handed.
The strap is a plain velcro hose strap used to secure garden hoses, can be found in your local hardware superstore. A hole is melted with a soldering iron for the mounting screw of the ULCS ball. The rest of the strap is threaded down the handle and out the bottom. Not as earth shattering 
a mod as my 10D to 5D conversion, but I believe it to be very functional.
Total cost, $5, and a couple of pricked fingers.
Cheers!
Stu
