When I built my home 23 years ago the contractor would only install Weathershield products. I asked him to switch to Pella but he refused. He stated that the weathershield products were far superior to all other brands. I should have "FIRED" that builder. I allowed him to build my house and use the best wood and exterior clad doors and windows that they had at that time The Weathershield windows and especially the 4 section sliding patio door have been a disaster. We had numerous problems and the factory people and their REPS were a joke. We have lived with our bad decision since our house was built. I can't attest to the quality of their products today but when we bought them 23 years ago it was our biggest mistake.

Sounds like you are leaning towards the Integrity and that isn't a bad choice. Of the options you listed out, that seems like the best one to me as well. You should be able to order it with a clear interior and stain it yourself if you like as well. Integrity is probably my choice in your situation as well.

We built in 2021 and ended up with 5 multi-sliding doors from Euro-wall. We needed impact/hurricane rated doors. All of ours are 10 ft high to fit our 12 ft ceilings. Our largest is 6-panels and 18 ft wide. We also have 4-panels that are 12 ft wide and 2-panel that are 6 ft wide. Very happy with them, except one is missing weather stripping and we have been waiting forever for the window/door dealer to send their warranty crew out to make the repair.

General contractor who is coordinating the renovation work will be doing the install. He liked using Milgard but they aren't distributing to TX anymore since Covid, so we are trying to figure out a good alternative that isn't as costly as Western. Store-wise, we were going through a window distributor who had the Western on display and is a MI dealer, but didn't have any of their doors on display or in the warehouse. The 100-series, which i did see, looked cheap, and the glass was very dark , but the specs look pretty different vs the 400's.
