O.K. Which EL34's for a Dual Rectifier and Why?

[fishyfishfish]

Just wondering about the hot setup El34 for my Dual. I have tried JJEl34L, Mesa's brand, and Siemens (Only one pair) Just wondering what every body else is running, and what makes the tube appealing? Thanks in advance!

1) JJ KT77
2) =C= (SED) EL34
3) Tungsol EL34B
