Another little old lady comment from Krygowski. To shift downtube
shifters you have to pause pedalling.

 Oh fer fucks sake....yeah, that's great advice....'pause pedaling while shifting'....wow, what a fucking moron.
 

This causes the man behind you with
brifters to run into the back of you as you suddenly slow down.

 Not if they're paying attention, and it wouldn't have been any different if the guy behind had downtube shifters.
 

They did
have 10 speed downtube shifters. Since they were lighter than brifters
why did not some pro's with the emphasis on lighter and lighter weight use them?

 I don't recall any manufacturer marketing 10sp index down tube shifters. I'll concede I may just never have noticed, but the question about they the pro's would never use them is a really stupid strawman argument.
 First off, dipshit, You don't have to change cadence/power any more/less with down tube shifters than with integrated shifters.
 Second, It's the dynamic of being forced to sit that affects cadence and power. With downtube shifters you pretty much are forced to sit to shift. The reason pros don't use downtube shifters is that the ability to respond quickly and shift while out of the saddle trumps the weight savings. FWIW - some people who compete in hill climb events (e.g. https://bumpshillclimb.com/) do often still use downtube shifters for the weight savings. Many riders also use a single chain ring and a single brake (UCI rules don't apply to those races).
 

Day after day you have not added one thing to the group except stupid
statement after stupid statement.

 oh, you mean like " To shift downtube shifters you have to pause pedalling." ? Oh, wait, that was you.
 

Jobst's bike was 66 cm and made from 1" rather low grade steel compared
to what is available today.

 You have no fucking clue what Jobst rode. A rider of his caliber was most likely riding at least something along the lines of Columbus SL, which in the hands of a competent builder is a stiff as any steel frame made today. There have been numerous discussions in this forum about blind tests of steel bikes built with different grades of tubing where the winner was more often than not the lower grade tubing.
 

It was unbelievably flexy and with old
downtube shifters and I think it a miracle that he could keep it upright
when going around turns it would start flexing the frame and wheels (36
spoke) and he would have to counter steer it to keep it going in the
direction he wanted it to go.

 Unless you rode it - which we know you never did - you have no fucking clue how flexy it was or what it took to control it. FFS kunich, Day after day you have not added one thing to the group except stupid statement after stupid statement.
 Tell us again how your shifting improved after you got special campagnolo non-stretch shifter cables?
 

But you have never had experiences like that. Not that that is a negative
- riding within your pesonal and bike selection's capabilities - but why
do you pretend to give advice on these subjects?

 oh, you mean like " To shift downtube shifters you have to pause pedalling." ? Oh, wait, that was you.
  

Campagnolo and Shimano offered bar end Ten shifters which can be mounted on DT shift bosses. We've installed a handful of each (vs hundreds of Ergo/STi). An outlier format but not zero.
