I asked for cap recommendation for my Sli-80 F1 on the amp forum at the Audio Asylum site and got quite a range of recommendations. It's an interesting group with a lot of DIY experience that hangs out there.
I went with the Cardas caps, which are no longer in production but can probably still be found. The Audio Connection in Seattle had them a few months ago when I had the work done. I don't know if they sell them, though, John may be saving them for his repair business. He likes them a lot and recommended them very highly. He'd bought a large stock of them when he heard they would no longer be produced.
I agree with the recommendation to just listen for awhile before you start upgrading. I did the swap because one of the original Jensen paper in oil caps failed, not because I was unhappy with the sound.
