I admit I love the B.L.U.E. Kiwi, but I'm not sure but what it's because it's a nice shade of bright Irish green and I want to believe it will make my mics sound better. Can I really hear a difference? Awww, I wish you wouldn't ask that!
How about this: if I feel more secure with a cable that cost $50 instead of $20, then paying $30 more for a sense of security is relatively cheap therapy. 
Buy the Blueberry, if you want it, and then YOU can write an honest but almost useless response like mine! ;-) Hopefully, one of the make-them-yourself people will step in now to rescue this thread.
Best wishes,
