Sarah, you write a compelling story. The problem is that Plexur, Grafton, and Magnifuse, whether injectable, moldable or sprayable are all just minor and not hugely meaningful variations on an old theme, certainly not something as potent as BMP. Add to that that these products compete in an extremely noisy market with 250 plus entrants for which a lot of false claims are being made being made, and that they are being sold by a commercial organization which has not shown much acuity over the past 5+ years, and the optimism wanes. I promise I won't tell you "I told you so" later.
