Thanks for the update on the STC cost. I haven't been closely following the pricing since the ship I'm buying has already been converted.
True about the 5 year life and 1200 hr inspections, but the Lamiflex bearings also have a 5 year life and I've heard from other Enstrom owners that they seldom survive the full 5, so overall it sounds like an improvement to me. I've also heard (from owners) the TT straps give a smoother ride and don't get out of track, but I don't (yet) have any experience with that.
