There is a consideration to do when comparing high wind pressure horn with lower pressure tubas and then extrapolating to bass trombones:
The bassbones will take the wide airstream of the latter AND demand the pressure of the former. Engineers will draw their own conclusions about air demand.
If you want to be a valve artist on trombone, then take a Bb-Gb-F-D model. that will basically allow you to stay within the length of the 4 first positions for all notes but for the hardest one: low B natural, which call for both valves + something similar to a fifth.
Both my bassbones are set up that way and allow me to play the pedal Bb both open and with both valves + a very long 7th. In fact slurring between these to versions of the same low Bb is a formidable exercise in egality and legato.
King 7B is among the lighter bassbones. It will sound bighter on lower dynamics, than do the various tanks from Bach. A problem might be, that King 7B's are rare on the used market, as people tend to keep them.
Thayer and Hagmann valves will reduce resistance. And empty your lungs.
