I like the Groove Tubes 12AX7-M in V1, and the EH 12AX7s or Mesas for the rest.
I use the Winged C 6L6/EL34 combination, and these have proven very durable, and I love the tone.
I too find the JJs too dark when used all the way through the amp. I think their power tubes are a little too fragile for use in a high power combo. They are better for heads.
