Once up to speed the wind foil over the roof is going to pull any soft top up and tight. Our rear side windows stay a little wavy at speed but it never bothered me. I'm in Charlotte NC so the temps rarely get bad plus the Bronco is not a daily driver. We've been in both soft and hard tops, my wife and I both prefer the soft top for its versatility. I'll admit we have the Trektop on order but just because we like the larger roof opening when thrown back and prefer the fastback look but find nothing wrong with the factory soft top.
The first time it's warm and you unlatch the top and open it you'll forget all about the MIC and it's issues. If we had to order again we'd go soft top 100%.
