For $650 I wouldn't expect great wheels on a hybrid with Shimano 105 derailleurs. You can search for reviews on these wheels. I wouldn't be worried about trueness at your weight. Seems like the bearings are more of an issue on these particular wheels. Just spin them by hand and listen for issues at home a couple times a month. With any luck you can get several thousand miles out of them before you need to think about replacing them.
