The consensus around my club is that all of the 24 series classifiers have excessively high standards. We have a couple of genuine GM level shooters who have not been able to get past A class on some of these.
I imagine there will be some refinement on these, sooner or later.
The 24 series do indeed seem to have pretty high HHFs.
For those interested in getting this data free, check out hitfactor.info (same as the howler monkey link on the first page).

24-08 with a G19 today for 7.7 HF.
Somehow I don't think this series will become very popular.
Doesn't read posts longer than two paragraphs.
Clubs choose which classifiers to use, right? How does USPSA encourage the use of a wide variety of classifiers?
The clubs choose. I don't think the org really does anything to encourage the use of a wide variety. Looking at data from hitfactor.info and looking at the number of scores on file for various classifiers in different divisions you will find a lot of commonality in the most popular classifiers. What is somewhat interesting is to look at the divisions in order of introduction. As data is added over time, you can see the way the use of some classifiers has changed over time. For example, the top 5 Classifiers by division:
Open: 06-03, 13-05, 99-11, 18-04, 18-07
Limited: 06-03, 99-11, 13-05, 13-04, 18-04
Production: 99-11, 06-03, 13-05, 13-04, 99-10
Carry Optics: 06-03, 19-01, 13-05, 18-04, 22-04
Limited Optics: 23-02, 23-01, 22-04, 22-06, 21-01
There is reasonable commonality between open, limited, and production. There is some commonality between those divisions and carry optics. there is no commonality between the other divisions and limited optics. 06-03 is the 7th most popular LO classifier. As a snapshot in time, I think the LO data suggests a movement towards the newer "stage style" classifiers and away from the older "stand and deliver" ones. The newer classifiers are probably more relatable to actual match performance. I imagine we will see some of this creep into Carry Optics, but for references, 06-03 has 9,344 scores in CO, so it will take a long time for the stage style ones to catch up (especially with the 23 and 24 series currently suspended).
My guess is that you see clubs wanting to use the newer stuff since a stand and deliver classifier that might only be 12 rounds is pretty low points value, chews up a stage in their match, and only matters to the people trying to earn and improve their classification. I shot an all classifier match this summer and there were four stage style classifiers and two stand and deliver style.
