What drinks should I keep in my home bar?

Currently I have the basics based on personal preference, Single malt scotch (Glenlivet 18 year & glenlivet 21 year), Tequila (Patron silver), Gin (Tanqueray No. 10 & regular tanquray), Brandy (Presidente), Rum (Captian morgan & Pyrat). I'm currently missing vodka cause I've never really liked it but am planing on picking up some of that (Maybe greygoose?) any recommendations on that would be much appreciated, I love mixed drinks and am looking at getting more into them and stopping drinking beer all together.
