My preference is for T6s too. Significantly wider field; good edge correction; adequate eye relief; great on-axis sharpness.
I think the idea of the 11mm T6 has merit too btw. This would give you 109x, 0.75 degree true field, with 2.3mm exit pupil; all pretty much ideal for deep sky observing on many objects such as galaxies and globulars. And if you barlowed that, you might possibly make both your 6mm Radian & 8mm Hyperion redundant.
