No input on the tripods, but I got a Sirui VH-5 Fluid drive head right before heading to moose camp and used it hard for two weeks. Used a combination of different spotters, bins (especially the 18x56 Vortex Razor UHD) and it was incredible. Had a bunch of different people using different variations and there were no negatives found. Well, I would prefer not needing an Allen wrench to attach the optic... but it does stay tight.

It replaced the "industry standard" Manfrotto MMH500AH head. Nothing wrong with the Manfrotto, but it is a lot bigger.

I just ordered the VH-10 for another tripod. I sometimes use heavy camera set-ups and I think this will be the real deal for the purpose. It is amazing how smooth the fluid drive heads are in use.
