I have a mixture of rein, febi, and genuine. Basically whatever was available. I've now replaced every coolant hose in the system with new at 15y. No issues finally.
I did the same, all new hoses when I replaced my turbos. My one suggestion is to rub a thin film of silicone lubricant on the hose attachment o-rings. Makes installation much easier and reduces the risk of damaging or rolling the o-rings.
