I had developed a great aero hydration/computer mount system a while back. The mold cost was 45K so I decided to wait. We then tested most of the products on the market. The Profile Design FC35 was the fastest in its low position. Then PD changed the velcro attachment straps to fixed hard plastic and that made the system not work well (thats why I took that product off the website), the next fastest system is a simple BTA like Xlab which also has the computer mount and velcro straps that attach to the extension tubes. Those straps and that system also makes the whole front end nice and secure if you use a lot of spacers.
