Yep the Elkheart was one of the bows I looked at when drawing this up. I wanted the forward handle but with the longer length to cover for my poor form... :D
Usually when the string angle goes past square the bow will begin to stack . That is, the weight will become more per inch than before that point.
I'm thinking since the string angle is so low at 28" I'm not getting nearly all out of her that is possible. But, with the stack I used being similar to my other d/ r and coming in 15 lbs heavier, it may be quicker due to lighter limbs for weight obtained for the stack. :p
