Geoff,
Don't think you will get a rush of answers on that one. I suspect most find a 2.5mm exit pupil too small unless it has the advantage of being really compact (or very good). A couple of years ago I tried a bunch of more compact pairs, mostly 8x, that included the Olympus and one of the Opticrons, but I'm not sure if it was the Taiga. I thought the Olympus was very good, second only to the Bushnell 7x26 which is about 4x the price.
