I use the Bestop Safari, Windjammer and Duster combo. (No drill header bar.) I'm very happy with them until it rains when parked. While driving, there is no water getting through. When parked, the seatbelts get wet and when it rains enough, the floor gets pretty wet. (It has to be a heavy overnight downpour.)
Without the Windjammer, it gets noisy. If you don't need to chat on the phone, no big deal.
The Bestop may not be the best brand. I don't know if there are many options??
Picture is when I have passengers.. Safari top only
