I definitely wouldn't consider VO5 sufficient for a rinse-out. The drugstore conditioners that I've found to have the best moisture and slip are: GVP Conditioning Balm (at Sally's), some of the L'Oreal Ever lines (you would need to check individual labels because some of their conditioners are cone-free but others aren't), some of the Garnier Fructis conditioners (I used to know which ones are CG, but can't think of them now, but there are a few).
