Silicone vs. Latex Foley catheter use.

Hi all. In our facility we are considering changing from a Bard Latex IC foley catheter to a Kendall 100% silicone latex catheter setup. I was wondering if any one has any experience with problems using the 100% silicone catheters. Primarily looking at increased infection rates so I thought this would be the group to ask. I case it makes a difference the kendall product would be about 40% cheaper. So administration is on me to approve this change. However the physicians are reluctant. So any material you could refer me to one way or the other would help.
