I have swiftech and koolance in my system .

Swiftech rads and pumps, koolance blocks and fittings.

both are top notch at what they are, but those koolance fittings are just sweet. It's hard to tell the difference in pictures but they just seem a notch above when using them quality and ease of use.

Never considered anything but swiftech rads and the mcp-35x is great.

You need to look at what is now not what was.
