The F4 and the FCX which I have both are easy to pull the rope through. The cost is over 100 dollars and the FCX is more expensive than the F4. I have both the Grigri plus and the Madrock safeguard with Cayon Elite andI think the F4 has been discussed recently. I saw the video a while back and thought it was pretty cool. I think the reason it will probably not replace the safeguard or Grigri is that the rope has to be fed through the holes manually and so the F4 is basically a bail out device, designed for firefighters to have so they can get out of a building in an emergence. I think that the price, about $75, will stifle the acceptance of an F4 over a slightly more expensive but more adaptable unit like the safeguard. If the F4 we like $30 more people might try it. I could be mistaken.
I am always happy to see videos from the New York Saddle Hunters. They got me into Ddrt. I just wish Ddrt was more applicable for me around here.
C-IV rope but I perfer the 8mm rope and the FCX. There are no internal parts to fail on either the FCX or the F4.
