Fuji G/GL690 and GW690 - Same IQ?

Tripods? Just depends. Today I had in my pack both a P67 with a big 300 EDIF and my Fuji 6X9 RF. I didn't use either of my ordinary MF-worthy tripods, but one of my big ones customarily used for the 8X10 camera. If I had a 165 or 200 tele instead, no problem. But that big 300 is in a whole different league in terms of keeping it stable and free of any vibration risk. The Fuji RF is quite easy to support per se. Whatever works well with a serious 35mm camera should work for it too. But I still want enough mass to a tripod to keep that itself breeze resistant; no toys.
