Good/bad experiences with mounts for travel?

I’ve been thinking about putting together a rig for travel, as even my smallest current setup is not transportable by commercial air.

I can readily sort through camera, optics, etc. options but would like to hear what others have used for travel mounts - good and bad experiences. Harmonic drive/strain wave mounts are likely to give the most bang per pound and are fairly compact (I own a larger WarpAstron one now), but do any of you have experience with specific ones that you have used for travel?

Thanks,

Jeff
