i use rollers as well, and would highly recommend them. you can get out of the saddle, but you REALLY have to be smooth when you initially stand, and you risk the embarrassment of riding off the front, straight into the tv. you will develop a very smooth stroke on rollers and you can impress your riding buddies at the beginning of next season by sitting up in the saddle in the middle of a paceline and taking a drink without changing your stroke.
