I noticed that with BrianBrave's solution the IC gets the stock resevoir, and the radiator gets the newly installed (smaller) tank.

Needswings is now offering on their website a solution that separates as well. But with needswings the radiator gets the stock resevoir tank, and the IC looks like it is on its own (no resevoir).

My SRT is a daily driver, so I do sometimes get stuck in traffic, but I also push the car. Which one of these would be the better setup?
I know the idea with the needswings style is to merely separate the IC and prevent the heat sink, but is the IC's fluid getting cooled enough?
And with Brian's is the radiator running too hot for daily use?

Thanks in advance,
Steve
