To me over the years since the inception of remote needles it has become apparent to me that the needle valve location has very little to do with the number of physical propellor incursions. Actually argueably a remote needle may aggravate carelessness around a propellor.

Most physical incursions seems to be caused by carelessness doing other things around a running engine.

As far as whether or not I like remote needles is kind of pointless since the majority of manufactures seem to have embraced them. I do like the needles used by TT on most of their engines that are angled rearward by twenty degrees or so.
