I too, use a hard sided suitcase, and love it. I'm the only one I know of that has named a suitcase. I know lots of people name their cars, so I see nothing wrong with calling my suitcase Big Red. Everyone knows who Big Red is. I think it's more secure, somehow, than a soft sided. I don't think I pack any different. If weight is no concern, you might try putting your clothes in a garbage bag, holding the opening of the bag over a vacuum nozzel, and vacuuming all the air out. Close it with a snap closure or a twist tie. Do this just before you are ready to lock up the suitcase. You will find you can put a lot more into the suitcase. If air gets in the bag, which it will, it won't expand any more than the size of your suitcase. Mind you, this method won't work if you are planning on buying a lot of souviniers (sp). I usually pack clothes that are disposable, so I don't have to bring them home, and have room for extra purchases. If customs make you open up, you can always sit on it to get it closed again.
