I guess I'm just a SWB kind of guy. I've tried trikes and found them slow, I've tried LWBs and found them awkward. But SWBs seem to handle more nearly like an upright, and putting them down really low gives them a bit of LWB-type awkwardness at low speeds but makes them amazingly fast. For me, speed always seems to win out; not because I'm always running around at 30 mph, but because that capability means I can loaf more while keeping up with my riding group.
