I'm looking for a windshield for my new vstar. considering a slipstream spitfire vs. a memphis shades pop top. they both look similar. they both get equal reviews. the mounting system on the memphis looks much more substantial. of course, the memphis is 3X the price. any comments? oh, most of the time I commute off-highway. this is more for the occasional trip and if I know that rain is in the air
