i know why i personally don't like dual pivots-- they almost always feel mushy, and while they stop okay.. they just don't feel like the brakes i had on bikes during the 80's. look for an old set of dia compe g's or something comparable, spend a few bucks, set 'em tight with a classic pair of DC levers, and be done with it. cheap and feel great.
i still contend that single pivots, while maybe marginally fussier-- have twice the spring power, and snap like no dualies i've ever felt.

I'm with you, too, bianchigirll. They're good brakes, and I have a set not yet installed, but I'm trying to hold off using them. Single pivot sidepulls are the simplest brake around, and you never have to adjust the pads after the first time.
I have a feeling dual pivots solved a problem no one really had. Or they compensated for the fact that people don't know how to center single pivots. Not that they're bad, but the change seems unnecessary to me.

If you want to stay with a classic style, these work on both recessed or nutted mounting.

No one cares
purdy! I'm sure someone already mentioned this, but you're dt cable stops are technically flipped I think. Barrels should be down from the screw on the opposite side. At least that's how I've always seen/done it. I'm sure it works just a well that way.

IMO, I think they are sexier so I want to swap out the the old dia-compes, that and I bent an arm on the front brake in a somewhat nasty crash a little over a week ago.

^ I didn't even notice they were "wrong" sided! That's so awesome! I've been looking for some logically sided long reach brakes for a while, and I may actually try just what you suggested. Polish them to a better finish. To me, it only makes sense to use brakes that are "wrong sided" considering my right hand is the one still on the brake when I'm signalling. I'd rather that be my dominate brake as well. If I have to stop hard in that situation, I'm probably in trouble either way, but at least I can slow down a little if I have my hand on the front brake.
Would you say they stop better than a decent pair of single pivots? These would be going on the bike that's going to get a lot of miles this summer, so I want something that has a good bit of stopping power.

I say that wrongsidedness can be a plus because a lot of British and French bikes that originally had centepulls have the rear brake cable stops on the drive side. I happen to prefer my front brake connected to the left lever, but the bike that has those brakes is the other way.
I'm not ready to say that they stop better than any of my single pivots, but I'm still using the original pads. Be sure to get the matching levers with quick releases from the same place.
Here's an example of when wrongsided sidepulls are an advantage:

Have you seen them in person? I have a set on a beater. They're crudely finished, have no quick release and are wrong sided. They don't need a quick release if you use levers that have them and the wrongsidedness can be a plus on some frames. I suppose they could be stripped and polished to a better finish. They work very well.

My experience is that on the same bike, the dual pivot ultegra brakes have a large improvement in stopping power as compared to the ultegra 600 tri-color (new pads both sets of brakes)... YMMV

Yeah... not even close. Take the 600 tri color brakes for example, I've had the single pivots and dual pivots, with the same pads, and the dual pivot ones are significantly better.
Stuff like the tektros will be better than any single pivot brakes, and the tektros are mediocre dual pivot brakes (sorry but they are). Some of the better dual pivot brakes are amazingly powerful compared to vintage brakes.

old pads? yup.. those can suck. but single pivot brakes can be JUST as powerful, and feel great. sounds like you mighta run into more than a few that were either badly set up, or had a passel of bikes with weinmann centerpulls...

I haven't actually used Weinmann centerpulls myself, but I thought some were supposed to be good stopping brakes? I've used the cheaper "universal" or whatever centerpulls and they'll stop you better than almost every single pivot brake I've used. I've only had one pair of single pivots that will easily brake hard enough to flip you over if you want them to. Is there a trick I'm missing to setting them up?

I don't have trouble centering any of my brakes. It's not difficult.

ultimately-- both work well-- but i'm primarily hasslin' mazdaspeed for untethered qualifiers they both have little intricacies of setup that make either work well. i clearly prefer muscle powered brakes and snappy levers from strong springs- there's probably some reason that that paradigm went out of fashion-- but i surely didn't agree to it.

Honestly the thought of single pivot brakes being better is pure curmudgeonry and is flat out wrong. At best they're almost as good as crappy dual pivot brakes, but a well set up pair of good dual pivot brakes is significantly more powerful than any set of side pull single pivot brake calipers, period.

You can convert any Tektro brake to nutted by using the hardware from those $14 800s that Bike Tools Etc is selling. Somebody posted a link to a site selling those brakes for $17 a set not long ago.

Here's a question for you fellas not terribly cozy with DP's......or, I guess, anyone really.....
I got some for my Trek 614 because I wanted to run 700c. The original DiaCompe 500's are maxed on on their reach. I read where many folks tend to believe this offers unneccessary and undesirable flex leading to poorer braking. True? Whether or not it is, would DP's....ie, the Tektro long reach R538's.......what I purchased.....offer better braking than the 500's at their max reach? Given equal pads and equal levers......Dia Compe aero levers and Kool stop salmon?

For me, I feel a difference and prefer DPs.
