It's a "whatever" thing. I just put a pair of 'em back on my Interloc because I'm riding with someone learning to ride on a tri bike and I thought I could instruct better from the same position. I originally bought 'em a couple years back for some century rides. I like 'em but am not tied to them. They provide another position and can be quite comfortable on long straight rides. I have...uhhhh...now I forget the name...but they're the "big name" brand, with the flip up pads (which can rattle a lot when you're not on them and the road is rough).
