Redhod, Jimi used .009s
Maybe sometimes. And I know his manager Mike Jeffery once told a British pop paper that he used straightforward Fender Rock'n'Roll strings. But I just know I talked about this subject once (in 1971) with Jeff Beck and he said he was astounded at the heavy strings on Jimi's guitar. I think you can find videos of Beck saying this.
The point I was making above is that Jimi changed his equipment quite a bit.
