Got my tester Shock Reduxes -- PLH comparison showed that the new ones were consistently high-PLH. I had a few earlier Shocks on my desk and compared -- one oldie had a lower PLH, and one oldie had a near-identical PLH to the new ones. So there are original Shocks out there shaped very much like the new ones. I imagine anyone who has been throwing the oldies with high PLH had few complaints about stability. ZJ's got a new one and will be testing it soon.
I hadn't seen any reports about any oldie looking similar to a newie, so there ya go. Again, the high-PLH oldie looks tasty-overstable just like the new ones.
