The "Demonstrated Cross Wind Component" is that which the Company Test Pilot (in this case Pipers Test Pilot) finds acceptable during the Certification process.
If you feel you are more capable than him, then you may find yourself having to prove this to the Insurance Company...we all know how they can wriggle given half a chance!
Interestingly, my old companys Ops Manual states a cross wind "limit" (slightly larger aircraft) and that was never exceeded. Gusts counted too.
This also seems to be the practice in Airlines...cannot have one company landing, one not, one pilot landing, one not..etc..etc.
So why not the same with puddle jumpers??

PS Bose-x: A 33kts "headwind" and 20 kts "crosswind" requires a steady windspeed of at least 40kts! (CRP 5 not to hand) In a C 152?!
