I don't want to mix sand with tubes, so the CCS is not considered.
My opinion.
The only use of sand is in HT power supply because the goal is to kill the ripple and get low Zout
The reason to use in this circuit the ECC88/6N6/6H30 ( 12BH7 and ECC82 is a possible alternative) is due the very good results, test lab and sonic performances and the easier arrangement of pcb.
The layout is more simply with only two sockets.
I have in the lab lot of pentode able to do this job but I prefer to use in the gain stages.
I repeat the 6H30 is fine for CF, for me
