YAOG, would you post a link to the soft wrap?
You can get it various places but here is a no brainer link on Amazon - woven split wrap by Alex Tech comes in different sizes, buy a size larger than you think to be sure of full overlap and good coverage. I just cut a piece using the largest diameter as long as the longest cable run and then run cables in and out as needed and some cables I will use a smaller diameter piece of wrap if there are more than one cable going in the same direction or location, like to the focuser which has USB, power and thermocouple cables. I used this stuff when I had the Skull Canyon i7 NUK on the tube and now with the ASIAIR PRO clamped to the top dovetail, it works and looks and feels very nice.
With the ASIAIR PRO I now only have two cables coming off the saddle, a power cord and an Ethernet cable. The Ethernet cable goes to the switch on a Slate AC750 Gigabit Ethernet nano router sitting on the tray and the power goes to the portable power pack on the ground. I use Ethernet to talk to the Losmandy G11 Gemini 2-mini controller. I use a Win10 Pro laptop, tablet or smartphone running the ASIAIR PRO app over the Slate's 5GHz. WiFi for mount, autoguider and camera control.
