OK guys. Thank you for advices! I forget about those.
Since the Apogee GTZ is coming, maybe i could get rid of Fuzion 2. I hope Swiftech is back!
XSPC Edge would be another good alternative but why the heck using Acrilic?§

Another tip : Tygon 3603 7/16ID 5/8OD is compatible with the Koolance 1/2 Compression fittings, but pretty hard to tighten.
