Graupner Propellers, any good?

[Intrepidation]

So I'm doing a Lipo upgrade for my SC, using the ESC and battery from the Super Cub LP. I was thinking of trying out new propellers. The GWS HD-1080 seems to be very well liked on here, but I was also curious about the Graupner GP10060 10x6 prop

Anyone have any experience or thoughts on these?

I had a brain fart and forgot to bring the paper with me for the type of prop this is. However I think I found it, but there's no hex indention for the lock but...is this the one, and if so, how would I mount it?
