I'm a 70deg fan, but alas I gave the 68deg a wide berth in favour of the 82deg which I'm contemplating buying (the 4.7mm). I've heard a long time ago they weren't in the same league.
Just still not enough comparative reviews out there on these eyepieces (the 82 & 100deg) for one to make a truly informed decision is there. Would love to know how they hold against a Baader Hyperion in a fast scope (forgetting about the fov difference, I'm talking about quality), but that's another topic all together, may have to resurrect an old thread of mine & bring it up.
