Roger had great success with the Pro Staff 90, winning 17 of his 20 grand slam singles titles using this frame but in 2014 Roger decided that he needed a racket with a bigger head size if he was to continue to compete at the highest level.
In this article, I will look at the main differences between Roger’s old Pro Staff 90 and his new RF97
Wilson Pro Staff 90 vs RF97 Comparison
Although the two rackets share many similarities e.g. 27in racket length, head light balance, and a 16 x 19 string pattern, there are still some major differences between the two frames that cause them to play very differently.
The most obvious difference between the Pro Staff 90 (or “PS90”) and the Pro Staff RF97 (or “RF97”) is their head sizes, which is one of the main reasons Roger made the switch as the bigger head size he has with his new RF97 allows him to stay in points for longer as it is a lot more forgiving than his old PS90.
Another big difference is the beam width of the two tennis rackets, with the PS90 being four inches thinner than the RF97.
The thinner beam width on the PS90 means it will be much harder to generate power on your shots and you will need good technique to have any chance of hitting winners with this racket.
In terms of weight, this isn’t a huge difference with the PS90 having a slightly lower strung and swing weight when compared with Roger’s new racket.
The two rackets also have similar frame stiffness ratings at 66 for the PS90 and 68 for the RF97.

Why did Roger Federer switch to the RF97?
There were a number of different reasons why Roger Federer made the switch including:
1. He wanted a more forgiving tennis racket
With his older rackets (PS90 and PS85), Roger used to hit a lot of shanked balls as the sweet spot on these rackets was very small.
The RF97 with its bigger head size and sweet spot helped Roger to reduce the number of shanked balls he hit in a match.
2. To help improve his consistency on his backhand side
Once he made the switch to the RF97, Roger’s backhand was much less of a weakness as he was better able to deal with high balls hit to his backhand.
3. To help him get more power on his serves
Although Roger’s serve was always a strength throughout his career, the bigger head size and the thicker beam width of the RF97 helped him get more power on his serves.
When did Federer first use the RF97?
Roger used a matte black prototype of the RF97 at the Brisbane International Tournament in January 2014.
When did Federer use the PS90?
Roger played with the PS90 from 2003 until the end of the 2013 ATP Season.
Can you still buy a PS90?
The PS90 is no longer produced by Wilson but you can find PS90 rackets for sale on sites like eBay.
Which tennis racket is better for recreational players?
Neither of these tennis rackets is suitable for recreational players as they are way too heavy for the average player. But if you really wanted to give one a go, then the RF97 is definitely the more appropriate racket to try as it has a much bigger sweet spot and a good bit more power than the PS90.
