What criteria do you use when choosing an applicator system for cervical brachytherapy patients?  

For example, how do you decide between applicators such as tandem and ovoid versus tandem split ring insertion for cervical brachytherapy patients?  Is it based on institutional preference, or do you have clinical experience with one being advantageous to the other in regards to bladder and rectal dose?
