Are there any studies, statistics or measurable impact of using mixed fonts on landing pages?

One of our landing pages is using five variations of the Arial font where size, strength (bold, italics) and color all vary. One camp internally believes that this okay, whereas another camp wants to standardize the presentation where there's less variance (such as a heading as one and the body copy as another).

Have you been through a similar trial or test in the past? I've seen some instances of a Marketing Sherpa study on the topic, but no real numbers to support one thing or another.

I've attached an example image of our current LP. I have a lot of strong opinions on a number of items - but we're looking to have an immediate internal discussion on the font issue first.

Thanks!

Standardising would be preferred, however as long as the font/text is easily readable you shouldn't be getting any penalties etc.

The person asking the question asked about studies, stats, or measurable impact. Do you have any of these you could share? You might otherwise risk getting thumbs down and appearing to be answering questions just for MozPoints, when you're responding to questions that are several months old and giving fairly general answers when specific details are requested.
