So, in the other thread, pilotdog68 proposed a tripod tail end like this one:

It would served as a middle way between those who are in favour of a semi-open tail, for better thumb access, and those who prefer a fully closed tail, for better stability whilst tailstanding. The tripod cut would provide both a good thumb access and a satisfying stability.
Objections were put forward as to its potential high cost, due to the machining involved in cutting titanium.
I think it would be worthwile to at least get a quote for this tripod cut, so we have a precise idea of the price premium it would incur. Also, if aluminium or copper versions of the host were to be made, price would no longer be a barrier for this cut.
