Jim,

I did locate the Finder datasheet on the Newark/Farnell website.  Watch for text wrap:

http://www.farnell.com/datasheets/2611932.pdf?_ga=2.102231233.1928605109.1538931238-590108331.1506213021

Note that specified operate/release time is "7/3 ms (12/4 ms sensitive)." It may be a well-made relay and could serve for the amp's antenna output switching function, but for T/R, it would be way down on my list among relay candidates.  

If the Flex amp is specified to work with a 20 ms RF turn-on delay, Flex's spec may be conservative -- or it's comprised of the relay time plus an additional software or hardware transition time.  I suspect these relays would settle in time for fast semi-break-in.  But for my CW QSK operating, 20 ms is almost an eternity!
