I disagree. While I don't think there is any need to go 'over the top' there is no problem with a little extra security in a hotter primer. I've had hang fires with STS and WIN but never a CCIM.
In a perfect world, you have a perfect breach plug, it's 70 degrees, your flash channel is always perfectly clear and there is zero oil. I don't know about you, but I don't live in perfect world so a little extra security is not a bad thing in my mind.
