I have 19'' Classics without PASM on (sometimes) bumpy UK back roads. Its perfect and much more 'organic' than computer controlled PASM.

Give me a real spring and tuned damper rather than a computer controlled one any day of the week. How the standard suspension rides is part of the cars character.

I certainly don't find it too bumpy and enjoy the ride at all times.

The purists go for -20mm and an LSD on the 997 thus binning PASM as it has a detrimental impact on the 'on the limit handling' character.

Also, and I can't back this up with personal experience, but quite a few users of the PASM have reported an unusual feeling from the back of the car during rapid diection changes on challenging surfaces.

Cheers and good luck with the decision.
