Not to be condemning for everyone, but bins that require using MOLCET do not work well for me. They fatigue my arms quickly, and having deep-set eyes, I can't see the full FOV with the edge of the eyecup resting on my Simian brow, nor can I hold the bins snug and secure against my face if I stick the tilted eyecup under my brow -- it increases image shake (that would be less of a problem with IS bins, though it may cause "swimming").
OTOH, I put up with the uncomfortable eyecups of the SE because the image is impossible to beat with a roof unless I could afford to pay 3x-4x more. So if I found the image as stunning in the 10x42 IS L as I do the SE, perhaps I could learn to live with the pain (literally) of the oversized eyecups. However, given my druthers and a pocketful of hundred dollar bills, I'd rather buy a 10x42 SLC-HD, whose eyecups fit perfectly and whose ergonomics balance nicely in my hands (almost 9 oz. less weight than the IS, too).
I owned a 10x30 IS, so I know that I'd lose resolution w/out the IS feature, but the heft and balance of the SLC-HD are such that I found I could hold it very steady, steady enough not to find microvibrations annoying or distracting like I did with the 10x42 SE. If I ever hit the PowerBall, I'll buy both the IS L and SLC-HD and keep the one I like better.
Until then, I might settle on another 10x35 EII, which also steadies nicely in the hand for me and has a extra wide 70* AFOV.
