No way.
"Head uses surface area, flex of mast cup and friction for super friendly snug mast contact": no, it just uses friction. The "progressive vertical flex" concept is simply wrong: flex means that the farthest parts will not apply pressure, so only the central area of the cup will work.
Apart from that, the real nonsense in the Enigma boom concept is in the 'corner' in the planform: that means tension will concentrate there, making either for a weak point or for the need for extra reinforcement (= weight).
To me the Enigma boom looks like it's designed by schoolkids. Maybe 120 kg heavy, but still schoolkids. Sorry, but that is what I think.
I think the Maui front end is far from the best designed front end on the market, maybe if it was 1995, but we've all moved on since then. It's biggest drawback is that the clamp is not hinged, it relies on you flexing the plastic around the mast each time you fit/remove the boom. Not only does this fatigue the plastic over time it's also a pain in the arse...there are not many booms on the market that still use this method, i'm sure they have their reasons but most of us have moved on. It's also bulky and heavy compared to the other options now available.
Now while the new Severne front end isn't perfect it's definitely significantly better than the Maui front end if ultimate stiffness isn't your sole measure; The Maui front end will probably win this because it's the size of a house...but it's over engineered for almost all applications. Sure, there's a some marketing fluff terms used in the Severne vid but ultimately there is some legitimacy to their design principle, similar methods RE the surface and engagement area are also successfully used by other manufacturers.
The only issue that I can see with the Severne front end is that the rope clamp could do with a bit of a redesign. Inherently the design puts the rope clamp hinge into single shear at both ends (this is unavoidable) but I think they've gone a bit thin/poor load paths with the design of the end of the clamp, where it meets the hinge pin at each end. When a load is applied to clamp the boom (not crazy pressure here) there is a fair bit of flex there in the plastic, which bends the clamp out at each end of the pin. It's hard to explain and tbh it's probably not a huge issue but it puts that pin under more bending at each end that is necessary and is generally not an optimal design. As I said though it's yet to cause an actual problem.
*Corollary: I would struggle to suggest anyone buy a Pryde boom because I've broken 4 (that's all i'll say) but their 'winged' carbon rear end is a straight up work of art. No one makes a rear end that is even close to as good as that...not even close. Their boom head is also pretty pro...bits in between though, sketchy.
*Disclaimer: I own a Servene Engima Wave boom. Personally I think it's the best wave boom money can buy if weight, function and feel are your primary measures.
