In my experience I can't be set up on most of the smaller sized 650 or 700c wheeled bikes, cuz either they steepen the seat tube too much for me (which only lengthens the reach since you need to slide your saddle back 1 cm per degree of STA to get the same position), or they have so much trail that the handling is too sluggish. So, I just picked up a 2003 steel isis, 19" but with the 700/24" wheel, 73 degree STA, 49 cm TT) for a song on ebay that I sent to a framebuilder to install s/s couplers and am building as a travel bike. In fact, she shipped today so I will let you know how I like her.
I was a bit worried about the STA as I believe my 19' classic is a 73 degree and I love it. But the 19.5 tt on the classic is a bit too short for me unless I'm happy sitting quite upright (I have short legs/long torso/short arms). My 19.5 tt Specialized feels right in length, but it's got a 76 degree STA which really works on the girly bits on long rides (and makes the tt feel longer as you mentioned). I figured the 74 degree STA with the longer tt on the 19' Isis should be right. I just hope that 74 feels as much improved over 76 as I am guessing!

I'll definitely let you know how it works out!
