What brand of nylon or plastic 2" spinner fits up to nose ring like a typical aluminum spinner. I don't like the extra flashing that a dubro spinner has. Please no "Great Planes" with the aluminum backplate.

Other than the GP spinners with aluminum backplates, plastic spinners are typically much heavier than aluminum spinners from Randy Aero, Tru-Turn and Dave Brown. If you need the nose-weight, continue as you are. If you happen to need a 3-blade spinner, Mike Haverly has successfully joined an aluminum backplate from the GP spinner and a 3-blade DuBro cone. I'd be more thinking of making a new aluminum backplate for the DuBro cone. Epoxying and/or screwing the backplate to the prop driver is always a good idea, IMO.
The problem with plastic backplates is that they are so thick that you'll run out of threads on the crankshaft on many engines, plus they tend to kick the prop loose occasionally...almost always on official flights.
Regarding those CF spinners...both Tru-Turn and Dave Brown sell adapters that usually will work or are a good start. I have had to re-machine adapters and spinner cones to make them all behave together. Boring out the counterbore in the spinner cone of a Chinese aluminum (metric) spinner to fit an SAE socket head screw isn't so much fun. Probably even worse if it's CF. I think all the adapters made here take an SAE screw thread. It might be possible to rework one to use a smaller or metric screw with the use of a Helicoil or Keensert.
