I just saw these and am going to test some soon. They make a "deep six" in 125gr that will match up great with the new Easton Axix traditional wood grain arrows.
While Dr. Ashby has his followers and I've read all the tests, many broadhead makers themselves, after many years of tests, can show that short and stout out penentrates a longer single bevel, especially with lower weight bows, as has also been my experience with several hundred bow kills.
For example, the short and stout Steelforce Phathead is still about the only head I know of to get a passthru on a giraffe.
But to each his own.
I think these Solid Heads are going to be fantastic matched up with the new Axis arrows and light weight bows.
