Focusing screen for Rolleiflex 2.8E (v1) - Maxwell, Beattie, Oleson, or .. ?

I have a 2.8E2 with a Rollei 6001 screen. Huge improvement. If you lack eagle vision I recommend a focus aid incorporated in the screen.

These are light weight cameras but work great on a tripod to max out image quality. Use the original neck strap and stabilize the camera by taking up the slack. Set the camera on a solid surface and use its timer. With a neck strap set a preset focus and walk city sidewalks glancing at the screen and click away. Folks will miss you are photographing.
