I have just returned from a vacation in Singapore. I took a Televue 76mm this time, and I was delighted with the ease and cleanliness of a 4" split of alpha Cru (Acrux) with a Nagler T6 9mm. In previous years I had brought along a Televue 60mm and did not pick up that split which I know should be possible with a 60mm. I think the jump from 60mm to 76mm was quite worthwhile in terms of increased resolution and brightness, factoring in the increase in weight and size (I'm glad I did not get a Tv-85!). I took it on the plane with no issues from any airport screeners.
I had thought long and hard about a WO or AT Tech scope, but the new 66SD I owned briefly was quite decent widefield but started giving up as magnification was increased. It simply could not compare with the TV 60mmAPO at high mags. With portable travel scopes, it is useful to have good performance at both ends of the magnification scale and I am very happy with the TV-76.
