Not a single cam...

I love the Insanity, but also drastically prefer the Destroyers over the Insanity. The new Insanity is better than the first model year though, so maybe they're working out the kinks. The first year insanity drawstroke felt terrible.

Best Single cam? Mathews all the way. Take your pick, I'm a Creed fan, the Heli-M is wicked skinny, but it doesn't do anything special for me. The old Z7 is still hard to beat.

But I will say this, I don't believe that the 'best single cam' bow is anywhere near the 'best bow on the market'. Bowtech's top my list, followed by the Mathews Monsters, especially the Chill, Hoyt Cam & 1/2...

I think you're painting yourself into a corner by knocking all of these great bows off of your list, so it begs the question:

Why are you ONLY looking at single cam bows?

Backing up a step: Do they even still make the Marquis?
