I picked untied as well. I personally don't enjoy being restrained in any way. I like to be able to move around and not have to worry that if I fall on the floor, I may dislocate my shoulder or break a bone because my hands are tied behind my back and I can't break my fall.

I do understand the appeal of being tied for many people though, as it may bring an extra sense of helplessness. Bondage is a much more well known fetish than BB, so a lot of people really dig it.
