I’ve seen loose and tight Troa tops and I wonder if the fit is partially due to how well it was installed. I agree that Julie’s samples looked like very high quality material. I called Troa and though they hadn’t done some of the custom work that Julie was going to do for me (I.e. thick top, lower, angled forward a bit), they had done other customizations, such as larger full zip out windows that are slightly tinted. They seemed keen to discuss my request.
I am about 4 months out from being ready to order a top and I might go with Troa. I’m going to be using custom bows so the tightness won’t necessarily be relevant for an OEM setup but I will report back my experience.
