best for someone with 27"/60lb specs??
Seeing you have short arms like I do

and want as much speed as you can get like I do

.
Then I would suggest the Black Knight yes it has a short brace height but with your draw lenght I dont think the brace will come into play as much as it would a 30 or 31" draw.
The specs for my 04 BK2 are 60lb 28" draw 214gr arrow 312fps 375gr arrow 288fps and a 400gr arrow 280 fps.
All I have on the string is the BT hush kit and a string loop.
The speed you will get will differ from mine depending on what else you have on the string.
In my testing so far the BK is deadly accurate in my hands and IMHO a very sweet forgiving bow that is extremely fast
