Wine galss choices..Which??

[SparklingSweet]

Can anyone give me a simple rule of thumb for which shape of wine glass is best with which wines? I seem to remembering reading once, somewhere, that certain wines are best served form as thin a glass as possible. While others should be served from thicker, goblet style glass ware. I know I prefer a very thin, fluted wine glass with my Asti Cinzano, or Banfi Rosa Regale, but not certain if I should serve ither to guests from this particular style stem ware. I hope someone can help....
