Rickresource Rickenbacker Forum

I would stick to Rickenbacker Nickel Round Wound. It is what they put on and I do not have a problem with them on either my 6 0r 12 strings.

If you like flat wounds and want the vintage vibe:

I have not read all three pages. Two pointers:
1) Purchase a set that has a wound 3rd unison G string so it will intonate properly with the octave plain G string. That excludes D'A and some others.
2) The low E string will have issues unless the octave E string is a large diameter compared to the unison E string. Here's what I did instead to keep a reasonable gauge to the octave low E string: order a blank saddle from RIC and file it to have the unison E string intonate off the back of the saddle and the octave string intonate off the front of the saddle. Issue solved.
