Yep, new designs can be tricky, all you can do is go with what you know. I agree with Bue, I dont think its a 'shelfer' by any means, its not bad past the wedge, you just dont want it to go any further. Worst case, you may go below target weight and possibly lose some of that nice static at the tip on this particular one as you slim it down.
The wedge length if fine, maybe heavier taper to push the flex past the wedge tip a little or less material(if any) removed at that point.
It's a great looking design, a few minor details and its gonna be a thumper!
