The only things I've ever heard is the danger factor of banner towing... I have not heard anything negative except on ASA's website, but after doing their interview they didn't scrutinize my logbook too much. They do go through it though (and I had none of the "non optimal" types of flying in there though)....
I would think it could be fun traveling, but could also get REAAAAALLY boring just doing laps day VFR. I do traffic watch a handful of times a month and that gets boring real quick. 2+ hours of day vfr with no specific destination makes me sleepy... Even if there are big things to look at (i.e. accidents and whatnot)....
If you are an MEI I would stick it out if you have multi students... Another option is maybe look at a school that has a charter department as well that lets the CFIs sit right seat. Multi time is going to be a big deal with the state of things today so I would definitely make that a priority.
