I've finally had time to watch all 3 in the series
The first -posted above is a bit of: this is caving (aimed at climbers)
The second is more the meat and potatoes of the trip/trips and the climbing/camping of "topless dome" (https://www.flickr.com/photos/realms_of_reality/1391932261/in/photostream/)
The third is for equipment nerds about load testing dome old mangy kit they discovered in there from the last people to have been in the very top section (who were the first ascenders Topless Dome (396') - Tumbling Rock Cave, AL - 1979 - Don Davison, Cheryl Jones)
probably for cavers the 2nd will be the most interesting, although slightly dissatisfying though as they didn't show the surveying up there or whether the rift at the back went higher(the whole point of the trip), maybe that will be covered in a caving channel in another video? Second video should be released soon and I'll post the link as many of you may enjoy it..
