...Recently on a caprice, I bought a pair of HGL's...
Sancho, have you broken your vow of no new optics purchases in 2008? If so, for shame!
As for me, I've struggled for a long time and almost given in several times to the desire to get the Nikon 8x32 HG/HGL, but thus far have successfully resisted. Optically, I find them perhaps the most pleasing of 8x32 roofs. Like all of Nikon's premium optics, they deliver a beautiful view, very comfortable on the eye. I especially like their generous eye relief and their relative insensitivity to eye placement for an 8x32--I feel like I can look around the view without getting blackouts, much as I can with an 8x42.
The only reason I've been able to resist the 8x32HGL is that I'm resolved to only buy binos that I will use (i.e. likely replace, at least in use, a binocular that I currently have, and I already have quite a fleet of 8x32 models). Every time I am tempted, I have to admit that despite liking its optics, I'd never choose to take the 8x32HGL into the field over what I already use. The optics of the HGL are not superior/different enough from other top 8x32 to tip the balance on their own, and the downsides are many:
-don't hang flat against my body
-weight is high for an 8x32, so may as well carry my Leica 8x42 Ultravid instead
-I don't like the ergonomics very well, certainly not as much as the Swarovski 8x32 EL or Leica 8x32 Ultra/Trinovid BA
-close focus is excellent, but not as good as Zeiss 8x32 FL for butterflies
-minimum interpupillary is 56 mm so I can't share casual views w/wife or kids like I can w/the Zeiss (52 mm minimum).
-from what I've seen, their exterior (rubber armoring, eyecups) doesn't hold up very well over time, whereas Swarovski, Leica and Zeiss have proven themselves superb.
As for Kimmo's reviews in Alula, they are of course subjective, but I value them above all other reviews of optics that I've ever seen (yes, even Steve Ingraham's). Why? (1) Because as far as I can tell, his reviews accord _perfectly_ with my own assessments--maybe we fortuitously have the same eye-brain programming? (2) His reviews are incredibly thorough--he seems to have used the binoculars he reviews for long enough and in varied enough circumstances that he discovers their idiosyncracies, weak points, strengths. (3) His reviews are admirably consistent and level-headed without being dispassionate (Too many reviewers seem to get infatuated with the flavor of the day). (4) Related to point 3, he usually provides some comparative perspective (including revisiting older, previously reviewed models) and shares his judgments as to how useful/important improvements or deficiencies are, practically speaking, for birding. The latter, though only one person's opinion, I find very refreshing, because he seems to maintain a sensible perspective as to the actual magnitudes of differences. Some other reviewers have a tendency to put anything less than their favorite model of the day in the obsolete category, such that they may rave about a model one year and consider it not worth mentioning, mediocre, or trash the next.
