what "technique" do you recommend for temp "permanent" wiring? #67

good ideas come too late -- decided to prep a "moving text" display for upcoming (in 2.5 weeks) exhibit and was lucky to find your project! THANKS! I am about to order 4 32x32 matrices from adafruit (display should provide text readable from 3-5 meters) + RPi2 + probably a power supply(s) (or will just use some old PC supply). If I had time I would have ordered the active adapter of yours but can't cash out 80$ for speedy printing. What would you recommend for wiring up the data cable so it is not too horrid for "production" use for 5 days on a display (hanging on a back drape, with RPi hanging somewhere near)? may be smth like http://www.amazon.com/Phantom-YoYo-dupont-cable-female/dp/B00A6SOGC4/ref=sr_1_1?ie=UTF8&qid=1443501921&sr=8-1&keywords=GPIO+cable with males remapped directly into the hub75 leading to the matrix or should I fear (since would be passive) loosing ability to drive it by increasing the length of the wiring? Thank you in advance for any wisdom. cheers!

Ended up ordering/using Premium Female/Female Jumper Wires - 40 x 6" and it was very easy and for extended use I will probably splice/couple old 40pin IDE cable remapping into the Hub75. Now just need to figure out text aliasing (#69)
