The way most ppl do it is intuitively pair up a wing and one of its edges for all tredges then solve like a 4x4x4 and chain solve it. I don't like this that much. I again intuitively solve one tredge at a time. I think about it like this, there is usually one wing and the corresponding edge together or just a few moves away then pair up the final wing and put it somewhere not to mess it up usually on U. Then I look for another wing edge pair together that are correct and repeat. I average usually about 4:2x.xx. If I pair up a wing with its tredge I get about 5-6 min. I just need to improve my center and solve time.
