Agreed, I much preferred RM's, shells and unknown/undervalued plays vs the whole chasing MOMO and flippin' strategy, which I also did for years, it just takes a tremendous amount of patience and certainly isn't for everyone.
Problem is RM's and shells aren't nearly as lucrative as they use to be, personally I think all those scam Chinese RM's a few years back ruined everything.
Plus,the whole JA_QC thing was such a total disaster it left me very wary of RM's and shells.
