My Also Rans PME PE runs at better than the seeing most nights...and holds a RCOS 14, AP155 and AP130 (at the same time) with payload to spare.
The ASA's are cool to be sure, but anyone who thinks you don't need to guide because the RA has minimal PE is deluded IMHO....I've seen stars drift several arc sec in DEC on many nights solely due seeing.
If you then accept guiding as a given, not matter how good the RA drive, then guiding *adaptively* is the next step....
