I'm a Grey Goose martini guy myself, extra dry (which means just a sniff of vermouth) - boring I know but certainly you should try it.
Speaking of trying things check out this website:
http://www.webtender.com/
A great online bartender's guide. One of the great features of this website is that you can plug in the bottles you have in your bar and it will give you a list of cocktails you can make - a great way for a novice bartender to experiment. Cheers!!
