If you settle for 3.5m TRS, you have GOT to go for 6 conductor in full 6 flat braid up to Y splitter then 2x 3 flat for L+R. It's craaaaaaazy good looking. 4 cond flat looks meh, but 8 flat is gorgeous. 6 gets to eat the cake and dance with the prom queen
I am guilty of buying for looks, but its not the smartest thing to do. Most of the time, my cable is under my shirt.
