@Tranqville - Yes, the Auxetic Rad MP could be very well worth waiting for. As for better feel of the Rad MP vs ET, I would say the jury is out on that -- the Rad would probably have slightly better feel from the slightly narrower beam and more concentrated sweet spot, but not by much. They both channel a decent amount of string bed feel straight to the handle, with little in the way of dampening.
If you don't mind the direct sales model for now (ie. outside of TW), another frame to keep your eye on is the just-released Furi Arma Pro 98 (
link). A quick look at the specs and initial feedback seems to indicate it could be
very relevant to what you're looking for: 98", 16x19, 8-throat main medium control/spin pattern, 22.5-24mm continuously variable beam (shout-out to Prince!), 31+cm unstrung / 32+cm strung balance, a listed 64RA that from initial feedback seems to play more like a 66-67 (more ProStaff/Pure Strike like), an upper 290's / 300-ish unstrung swing weight (so probably upper 320's-330+ strung swing weight).
All their faults aside (snail's pace narration, inaccurate specs, bland/non-descript verbal reviews, etc.), Tennis Spin just reviewed it very favorably, including coach Gu who went out of his way to mention incredible feel:
Note - it seems they got a high-spec sample of the AP98, so I would take the slightly high SW and head-heavier balance in context for now...
I'd say it's definitely worth bookmarking that frame for further observation, at the very least.
