So, I have never grown or smoked the menthol cut itself. I have grown several of the crosses he offers however. I feel the real value of his males is their transparency. Jet fuel Gelato, horchata, and the menthol are generations of the same line as he continues working it. In a cross with a highly inbred and focused plant, the result is errily consistent with the mother in flavor. I get really low phenotypic variation with his gear, which is a great thing for producers. So he's got a stud that you can cross to basically anything and you'll end up with moms taste, cookie dominant bud structure, and a vigor and veg speed more like the jet fuel.
The exception is when he hits something that's already a soup, not a very focused or inbred clone but a raw first generation poly hybrid. Compound tends to put out more of those (they are using the same males I guess). I grew one where the mom was like, white Tahoe amnesia cake or some shit, and that was the only one that threw a lot of different phenos, some basically just the dad.
