I've tried these two:

Ei (Elektronska Industrija Yugoslavia) EZ80 (stock tubes)
Tungsram EZ80

-- with Sylvania 6DJ8 drive tubes and Sylvania 7236 power tubes. With my setup, I couldn't make out any differences. Big disclaimer here, though, as I've only had the WA2 for about a month and this is my first tube amp. But at least I can say there wasn't a huge "amp-changing" difference like when I first tried Russian 6N13S (a.k.a. 6H13C) power tubes -- which in my setup are a lot less fatiguing and give warmer sound than the Sylvania 7236s.

omg.... sell me your tung sols......

Tungsols 5998 are regarded as some of the best driver tubes for the wa2 and are become as rare as hens teeth.

I'm not sure how recent your version is, based on your tube combo, I am guessing its second hand hence the 88cc and the 5998. I am not sure if you can roll the 88cc with 6922, but if you can, you cant go wrong with phillips sq (I believe rolling these tubes will have the greatest effect on using the amp as a preamp)

There is a tube on here somewhere regarding the rolling of tubes for WA2

I guess you're referring to this: Woo WA2 Tube Rolling Recommendations. It deals primarily with power tubes.

Try Mullard NOS square getter EZ80
Jack told me that many customers feel this tube has best synergy to Wa2.
Telefunken EZ80 couldn't deliver smooth sound when combining with Wa2.
Sometimes people substitute EZ80 with EZ81 but I think its sound is too laid back in Wa2.
However, there are many no-mullard-made EZ80s printing mullard,
be careful.....
