Yep, the US guys will almost universally recommend Penske over Ohlins, it's just a better part. Penskes can be fiddly to set up, I'm told- certainly the triple is, it's got so much adjustability that it'd be beyond most people to get a good setup. But they're more durable (longer service cycles) and the default setup suits more riders than with the Ohlins.
Coincidentally, me and Scooby Drew are messing about with 636 shocks in, amazing as it may seem, a 636... Putting hte newer SHowa into his older 636. Very similiar in dimensions, spring rate etc, but without the drwaback of being, frankly, rubbish and misspecced. The old 636 shock is a reasonable choice for the SV, actually works better than it does in the kwak, but not great... I've never tried this new one in an SV but it should work very well.
(hmm, he's left it in my garage, maybe I'll sneak it into mine while he's not looking and try it out
)
