did you ever try one with a pete models spinner backplate? It has no knorling ie smooth. I have heard that the knurled truturn and a tight nut works fine, but I have also heard that the CF spinner backplates being smooth(non-knurled) slips. I sent my backplate to pete models and had them knurl it, but the knurls are not as pronounced as a Trueturn. I am concerned about this because I have a $90 spinner, a $75 prop on a $1200 engine...

Mine is New in the fact I have never run it but it was manufactured a year ago. The ones made now will have a 10mm shaft and a 6 bolt pattern, it matches 3W and DA 100. The older version had a single 7/16 bolt and two short bolts that only engaged the spinner backplate.
