Well, as for the wires.... I've had in mind some of quick clips, but when i did approx. static calculation, the forces on one wire can easely excess 30 - 40 N (ca. 3 to 4 kilos of impulse force !!!). I wouldn't recommend using a plactic quick clips; maybe a metal one. As for attachements, there are two possibilities which comes in use for me:

My WACO:

Wires stay always attached on fuselage/center wing sections. Tighteners are on this section.
Wing part of wire is attached to a strut mount via additional aluminium plate and with screws and bolts. I know i look silly doing my "indian dance" around plane everytime when mounting wings, ..., but so far construction holds perfectly.


Other possibility for me was using a metal clips on both side of wire. But wing struts should be always attached with some safe and strong mount (screws ?!), so why not attaching a wire on wing section in a same time.

Here is a concept drawing of my wiring system...
