whats the best tubing to use, i did want 12mm E22 to fit EK and bitspower fittings, but after seeing some videos on tubing ive seen primochills tubing to be very tough and easier to use, hence the hammer test where one breaks easily and the other dont, but then i would have to use 13mm fittings which i think dont look as nice as there to bulky, can someone tell me who has used E22 tubing tell me if its a good tube to use .
