Rota GTR then if you really want them so badly. I'm sure the whole point of us not likely rota is simply because they're replica, meaning imitations. I'd much rather get second hand ones than get replica myself but that's just me (which is why I got mine second hand). But hey, with the argument of being stronger because its forged, it doesnt bother me because I doubt I'll ever drive in a way or make that much power to destroy the rims. Just for your info, those CR Kai I had before were sold to my friend for 1.5k, so these rims really only cost me 1.7k.
Anyway, I thought you like your rims? Why spend 3k+ on new ones when you dont have any issue with the current ones? I'm sure theres better places to spend that money on.
