ITA that it depends on how thick your conditioner is. I tend to prefer light to medium weight leave-ins because I'm also heavy handed, and I wanted my hair to be ultra bouncy when I rollerset (I'm natural now and don't do it). My mom and I always used Infusium, I also liked Aphogee Keratin Green Tea Restructurizer; both are liquid. An almost runny milky consistency is also good for me; I liked Giovanni DLI in the winter. I always used an oil blend just on the ends of the rollers; I used Profectiv's Growth Oil on the ends with good results. Good luck.
