Is over 10 year out of date too old for a racket??

I was wondering if pro’s will use dated rackets with a paint job?
I have a Yonex RDS 001 MP (Hewitt/Nalbandian era) it is clearly very out of date but I’m yet to find a racket I enjoy hitting as much as it. Think I got it around 2006?! I was wondering if I’m missing out on new technology or if the technology hasn’t changed too much over time?

Also.. any new models that closely resemble RDS 001??
