I had a lot of difficulty finding conditioners that I feel are moisturizing enough for my fine hair, too. I always thought if was because I'm low porosity.

I agree, the AO conditioners are pretty heavy. Others that I'd put in that range are: CJ jar conditioners, Komaza Califia Conditioner, Spiral Solutions Caitlin's Conditioner, Jasmine's Shea Butter Conditioner and Shescentit Green Tea & Hibiscus.
