I cant find one with 6 inside hole for Robinson, if you can pass me a part #?
thanks
Yes i use the 2 hole ones, but they also have 6 or 8 holes around the outside as well. I just use the 2 holes on the inside.
I use 111 and 115 from this page:

Why would you need 6 holes? more rotating mass. Actually I'm sourcing some short titanium screws and short aluminum screws so we can reduce rotating mass even further.
You really only need 2 screws.
