Yesterday, we installed the PRM optic in the suspension.  Today, we adjusted roll and suspended it.  It has a bit of a pitch which we will need to work out tomorrow - the top mass is ~level and the optic is ~level, but the middle mass is pitched.  So, it's either the top mass blades, or middle mass weight configuration inducing pitch.  WIll confer with others and make adjustments tomorrow.  Preliminary height measurements do not indicate any major height problems.  Final numbers/tols will come later after tweeked.
