A control player with good downward smashes used a 3U Nanoflare 1000Z for three years and loved it until it broke. Found the Nanoflare 800 Pro's shaft too soft by comparison.
“After 3 years I broke my 3u 1000z. I want an equally stiff racket and am brand agnostic. I loved my 1000z but am looking for something a little cheaper.”
