Push to Talk switch wire routing?

How have you routed your wiring from a stick mounted push to talk switch? I've seen some pictures of the wiring coming out of a small hold at the aft base of the stick. Is there any advantage in drilling through the thick horizontal 5/8" tube, and exiting either forward or aft? I've got dual sticks if that matters.

Thanks,

I went aft. Makes it easy to get under the seat pan and then route to the side to go up front. Wires are hidden under the stick boot.

Bryan,

Here's the other one I saw on the site. From ScottM-Sonex1629

He came out much lower, closer to the base. Was there a particular reason that you came out of the stick so high?

I also went aft>inside near the base of the stick on my dual-stick controls. It seemed to me this would result in minimal movement of the wire as the control stick is moved.

I went higher because the bending loads are lower up there, and it is still covered by the boot. There is no more motion as you secure the wire to the outside of the stick and just have a small service loop at the aileron pivot. Then I plan to run the wire down the stick frame and have another service loop for the elevator pivot.

Structurally it probably doesn't matter that much. Loads are low. But I'm an engineer and it made me happy to go higher.
