hard top is not something you take off on a whim if you are by yourself. If you have a hoist, ok, but it is too bulky to manage with 1 person. As for how often - really depends on what you have to replace it. I would do it as often as possible. Given we are both in CO, you know about the afternoon showers (almost guaranteed) so you will want a bikini or safari to have with you. Or, you can stay at 40+ and let the rain blow over the driver's compartment.
