 Possibly the best spinner on the market (IMO) is Tru-Turn.   They are 
expensive but once you try them  I think you will be willing to put out 
the extra bucks.  They come balanced, are extremely light (thats why 
Pattern flyers love them!), and look good.  I have not had one come loose.

The spinner, backplate and spinner bolt is packaged and sold separate from 
the hardware.  The hardware consists of the prop nut, a washer and bushing 
to adapt the backplate to the crankshaft.  There are prop nuts to support 
all thread diameters and pitch.  Tru-Turn recently introduced a double 
jam-nut prop nut assembly for the YS 120 which works extremely well.

BTW, I think it is recommended that metal spinners be used at RPM's above 
12,000.  I had a goldberg plastic spinner disintegrate on a YS .61 turning 
at 11K+, and that was during break-in!
