I'm voting for: do that!
Try for yourself and find out if you still like it.
I turned most of my trials into sprays. Including the Savage Beast trial. There is still a scent, absolutely. But I don't know how you will like/smell it.
From the full bottles I usually take 3 or 4ml and dilute that in 6/8ml pure alcohol. So there is still enough oil left and enough in the spray bottle to test that.
My "selfmade sprays" don't last as long as oils do. I'm not sure if the scents are getting 'weaker', because I still have to be careful not to spray too much on (scentwise).
