The Livespills were more along the line of IMs, not like blog entries, so they’re long-since gone.
I did find this relatively more recent post from CT about 666321: “6/6/6/3/2/1 is similar in that the sets of 3/2/1 are the heavy sets, the sets of 6 are conservative. They would use around 70-75% depending on the lift.”
It’s a set/rep scheme that you should be able to use with any strength-focused split (one, possibly two, main lifts per day).
