By contrast the DeLites have none of the Radian's shortcomings. Quite an engaging eyepiece to use surprisingly with just a 62 degree AFOV. In my field usage I compared them to my XWs and found they met or exceeded them across all my tests. Quite surprising.

Can't comment on the DeLite perse as I haven't look through one but having extensively used Radians and virtually every current eyepiece Televue make in a 7mm FL or close to it I can accept that the newer designs of Televue are certainly better than older designs. It would be pretty poor show if they didn't.
With these points in mind and putting aside the variables of AFOV and ER I haven't seen any Televue eyepiece which wasn't easily beaten in optical performance by some Japanese made simple ortho's which can be bought for about 25% the cost of most Televue eyepieces
IMHO extensive marketing is the key factor to the Televue production formula - look at every astronomy magazine who perpetually does all the full page advertising. I can't recall the last time I saw an advert for KK - ironically I am also even surprised when I come across ads for Takahashi
