Recommendation for very high bandwidth diff amp

I'm interested in driving a 100-ohm differential load (i.e., two 50 ohm lines, 180 degrees out of phase) at up to 6 GHz.  It looks like the ADL5565 might be a good candidate, but the data sheet seems to assume that it will be used at much lower frequencies as an ADC driver, working into a 200 ohm load.  Can anyone address the pros and cons of running the ADL5565 as a 100-ohm differential line driver?  What impact will the lower output Z have on parameters such as output swing?
