Makes sense. I've read through many posts here discussing the advantages and disadvantages of the 180 vs 195. While inconclusive (kind of like oil discussions  ), I was thinking about going to the 195 because 1) that was the stock thermostat configuration and 2) my engine rarely gets hotter than 195 - 200, but will bounce between 180 and 195, especially when not on highways and on the hilly roads where I live. I figured it might be better the reduce the temperature spread and keep the temp more consistent with less expansion/contraction. Maybe that doesn't matter, though, and if a higher temperature thermostat could potentially make my pressure situation worse, I'll keep it at 180.
