I tend to just use the same light conditioner for the CO wash part and for the conditioner part - if I use a heavier conditioner after the CO wash it seems to weigh me down.
What's interesting is that I recently reread the CG book. I totally adjusted the amounts to what the book said (for wavies) as I realized I was way overdoing it with the conditioner. A big difference and my hair has more body. I still low poo once a week or more if needed though, since I am a wavy not so much a curly.
Hair Type - medium to fine texture, high porosity, lots of it, type 2b/3a
