We use nothing but primes. In our first wedding, I did use a zoom for a few shots during the ceremony, but in retrospect, it wasn't necessary, and we sold it almost immediately after the wedding. For every wedding since then, we've used nothing but a 35, 50, and 85. Here's our most recent wedding as an example.
Why do we use primes during the ceremony? For the same reasons as during the other parts of the day: simplicity, low weight, low light, low DOF. I use the 35 pretty much exclusively while B uses the 50 for most of the day and pops on the 85 now and then.
