I agree with Olias. If you are not going to tube roll, I'd just get an Emission Labs 5U4G and the Princess, skip the Sylvania 7236's and call it a day. I'd stay away from the Sophia, even if you have to run with the stock rectifier for a while. I got the premium upgrade from Jack as it is listed on the web site when I got my WA22, and did not like the Sophia or the Sylvania. The princess is a good tube and I would get it from Jack, ditto the EL5U4G. He is very easy to deal with, and if there is a problem, he will do whatever it takes to make it right. When I replaced the Sophia with the EL5U4G it put everything on a whole new level.
If you are going to tube roll, Olias is right, the baseline is important; if you move too many tubes around at the same time, you'll never learn what each tube brings to the party.
