So how would you compare the LB to your other bands in terms of comfort and day to day wearability? Does it build up heat/sweat more or less than the SB or LL? Is the lack of ability to make mid-day minor adjustments an issue? Does it slide around on your arm?
Asking because I have the SB and LL (usually wear the LL), but I've been longing for the LB since Day 1. It is so perfectly matched to the SS watch and looks like a million bucks. I think it will be my xmas gift. But the LL is easy to adjust and that is one issue holding me back a bit.
I can't speak much about the leather loop, because mine is a generic version that I haven't worn much (I have a 38mm watch, so no official leather loop is available,) but the ability to adjust it incrementally is a great feature.
I've worn metal bracelets from Rolex and the like for a while, so I'm used to the relatively unadjustable nature of a metal bracelet. I wear them just tight enough to sit up above the wrist bone when I'm cold, and then, when my wrist swells, it gets tight, but not uncomfortable. There isn't a way to micro adjust the link bracelet, but the removable links themselves are pretty small, so getting a good fit isn't too hard. It's also good to experiment with how many adjustable links are on each side of the clasp, as that can adjust fit slightly.
As it stands now, I usually wear the link bracelet in day to day life. The bracelet doesn't get quite as sticky as the Sport band, but it is noticeably heavier and less adjustable, so I'd say they each have advantages. Based purely on comfort, while the link bracelet is fine to me, I'd have to give it to the Sport band (and likely most leather straps, too.)
I think it's good to have both, depending on the situation. If I know I'm going to do something a bit more athletic, I usually switch to the Sport band. For me, the link bracelet is the more durable, slightly less comfortable, slightly better looking choice.
