shimano 9sp dura ace 10sp tiagra compatibility

hi guys....im building up a winter bike and had a quick question....will a 10sp tiagra 4700 rear derailleur work with dura ace 9 sp 7700 downtube shifters in index mode ?
im guessing it will but i just wanted confirmation from some of the more knowledgeable folks here

thanks !

10 speed Tiagra has a cable pull ratio that is not cross compatible with older 9 and 10 speed shimano.

A 9 speed shimano MTB derailleur will work, and I think they are still widely available.

^^^what Darkmother said. 4700 is it's own cable pull (unfortunately) so you'd need those specific matching shifters for things to work correctly.

IMO i'd avoid any newer 9spd derailleur with a Shadow Plus style routing and opt for the older style like an XT RD-M751. They shift alot more smoothly in my shop experience.

Pretty confusing to look through but this page is the archive for their tech info.

This looks way more organized than it used to be though, someone is doing some good work on the website.
