The one piece is normally not as heavy as a TD. When it comes to traveling, the TD is far and a away the easier to deal with. I personally prefer two piece long bows, over three piece long bows. Just seem more traditional to me. I own two Hill TD longbows. Craig uses the sleeve system and only offers his TD bows with a straight grip. I have one with the smaller grip and one with the larger. There is very little difference. I also own a three piece TD recurve(Massie Model "M"). If your a traveling man, which I think you are, the TD bows just make more sense. Besides that, I find them to be a little more stable then their one piece counter part. Take your time and determine what is best for you.
