The 003 is far more light. It's very different. I found it unstable and too powerful at my level with the ball being hit hard at me. I play mens singles so the 003 wasn't really suitable for that. Sold it to a gal who is doing very well with it. She has a big wingspan and hits very flat with it, though there is access to a lot of spin with it. It's a great modern racquet with many subtle technologies built in. Nice paint job. Simply huge sweetspot. Great Yonex muted feel, v comfort.
