It definitely can be a slow search, but the best way to search is with numbers you are confident in.

In addition to the stack and reach article I linked, youtube is flush with videos that walk you thru how to accurately measure your current bikes stack and reach. Then if you just add the numbers you get for where your handlebars are(I assume your position is comfortable), you can be well on your way to finding a frame or bike with geometry that will work better than your Kestrel.

As a general comment, I have never seen a Kestrel road bike that is anything but race geometry. Kestrel Tri bikes, Kestrel TT bikes, Kestrel race road bikes- every Kestrel I have seen has had relatively aggressive geometry. Even the 'endurance' Kestrel model I saw online somewhere had pretty aggressive fit numbers. Point being- hopefully you can make a bike that has better stack and reach numbers look pretty good without having to resort to too much kludging(adjustable stem at high angle for example).
