Chaining grammar patterns in real contexts

I've been experimenting with chaining grammar patterns instead of isolated drills. I tested this by writing a mock 返品 request for a product that didn't 優れる in performance. My observation: using '～ものの' into '～につき' felt robotic at first, but after three trials, the logic flow improved. Has anyone else tested specific scenarios to see how grammar points actually bridge together in a real context?
