Heh. I think everyone on BMR loves bondage in some way or another, Rauk.
Blindfolding, in specific, is something I give a lot more credit to than most.
The biggest thing a lot of people fly over is the question of what to use. Blindfolds that are designed to be blindfolds can be comfortable, and are less likely to allow peeking without requiring you to pull too tight, but there's just something... visceral about using something that isn't. My personal go-to is a silk tie. The fabric is pleasant enough that it doesn't irritate or distract the sub, and has that spontaneous, sexy, raw feel.
The best part of it - typically amplified by any feelings of helplessness - is the fact that the lack of sight makes every other sense that much more sensitive. Every squeeze, every kiss, every thrust gets you more bang for your buck; pun intended.
One thing I don't enjoy, though, is tying a girl down. Or rope in general, for the same reason I don't use a paddle or a whip - you always want to use your hands. The most obvious reason being that its much harder to control your strength when you don't directly feel the recoil of the impact or the strength of the squeeze/knot - either you go too hard or you're so terrified of being too hard that you go in the opposite direction and its no fun. Always using your hands means that is never a problem and reduces the chance of a turn-off. Second point is the touch of flesh on flesh always feels more intimate, and the more frantically your hands are moving over your sub's body, pinning her breasts down when she arches, then her hips when she squirms, the more she experiences the subliminal feeling of being desired. And considering you can feel every reaction as it happens, don't be afraid to be a little rough so long as her body doesn't stiffen in response.
That's my two cents, at least.
