Yes, I remember doing this some time ago. I think it's just a result of a natural hoarding instinct. These days, I have too many (not as many as you though) scents and have no prospect of ever using most if any of them up, so that trait has vanished and in it's place is a reluctance to add more. It's a reluctance that is easily overcome due to curiosity and insatiablity. :P
These days I find myself using the newer acquisitions and having to force implementation of last years stocks.
They do provide variety though.
