My besttop bikini when attached to the the door surrounds actually keeps out most water even during a hard sideways rain. The only place I have had a problem is toward the windshield where the bikini is a little loose, I get a drop or two when strait down but nothing but more than a mist when driving.
The duster will keep most water out of the rear area, but the fabric around the roll bars will be out in the open. Can't say for the windjammer though, mine was just ordered.
