amazing, man!  You're really good at this...didn't you make a short little holmegaard last year?  With chinese writing painted on it?   I know what you mean about "low tension at brace"...a 57" yew holmegaard i made last summer felt the same...but still drew to 52# @ 27" and still snaps out arrows.  
Now, do it again!  This time with osage or locust or something like that...
