Aldila RIP Phenom

I am interested in the RIP Phenom 60s, I only see the 50 and 70 gram version on the Aldila site.

is the 60 gram version a "made for"?  Any experience with the Phenom?

Thanks

Phenom is available in 50, 60, 70, and 80.  My experience has been very good. Good stable feel.

Thanks for the reply
