Let me put it this way.. When the 8 blade WORKS it's fan-fucking-tastic. Shakes less, "easier" to work on provided the Mech's aren't chasing electronic gremlins, etc.. Only complaints with an "as advertised" system, is they lack the HUMMMMMMMMM that made the Hummer, well, the Hummer. I'd have to actually drive my happy ass into work and query OOMA, but the gripes per flight hour we have related to the 8 blade is something heinous. The E-2 has one of the worst man-hours to flight-hours ratio's I can remember, and that's giving an allowance for keeping all the wizard boxes in the back running. If we had CNS/ATM, it would probably eliminate about half of the coming back from FCF single engine I've experienced, because if it was a Code XX I could restart, and I'd only have to keep it off for Code YY and ZZ (not actual code numbers, but you get the idea)
