Wilson designed the 85 for Jimmy Connors in the first place! Pete Sampras plays with a Babalot racquet the last time I saw him play.
I do give you the Connors part, even though "Pete Sampras, who used the racquet for his entire professional career, established the reputation of the Pro Staff 85 (graphite/Kevlar) as a legendary racquet more than any other player" (wikipedia).
Federer is the least person to have its legacy. Connors, Edberg, even Mary Pierce would be better than RF.
It does look a bit like Tesla-Edison... let's go with Edison because he has charisma and is a celebrity. Tesla is a nut job, who couldn't land a contract, nobody likes him. Right?
