STI triple shifters. Do these newer shifters allow for trimming?

9 speed models support triming.

No. Some models are double only.

Ultegra is cheaper.

Yes; I found a web site selling Shimano...the Tiagra, 105 & Ultegra lines
STI shifters will work double or triple, the Dura Ace will not. It seems the
Dura Ace are built to a finer standard, so I'll go with it, as well as the
bottom bracket. Surprised to find DA is only 1/2 oz lighter than Ultegra!

Trimming in the middle ring only and if 9s and modern and shimano, both double
and triple. Some older DA is double only but all DA that say triple on it are
both.

DA and ultegra are a wash in terms of performance and reliability and
maintainability...not all that great IME.

I would seriously look at Centaur or Chorus from Campagnolo. Much more
intercompatible and repairable levers.

With my DA ST-7703 triple shifters, trimming works with both the
middle and large ring. I have two positions with both of those rings.

As far as "Dual Control", I think that refers to both shifting and
braking.

But, the DA has the 3 year warranty, where-as the rest of the line is
2 years. I seem to recall that the DA shifters use ball bearings,
while the rest have a bushing, I have no idea, if that matters. I got
some really good prices, when I bought my DA triple components, they
have since gone up, a lot.

If he hasn't already bought a Shimano rear derailleur, then he should
take a look at those options.

They guy who built up my bike with DA told me that the Ultegra bottom
bracket was more durable/better than the DA. So I have an Ultegra
bottom bracket, with the rest of the components DA.

Ultegra BB is easier to install and needs less maintenance after
installation. "More durable" is questionable.

Hi, that is the case with the DA BB for double, as it isn't a sealed
cartridge and it requires adjustment. The DA triple is a sealed
cartridge, of the same design as the Ultegra. I am using the DA BB
with my DA triple crank.
